This Shein swimsuits review will help you shop all the best Shein bikinis for 2021!  They have super cute swimsuits for summer at under $15 for both pieces!

shein swimsuits review 2021

Shein has really stepped up its game in the swimsuits department, offering figure flattering and trendy styles for all shapes and sizes at affordable prices!

I personally have a small bust most bikinis from mass retailers are too big in the chest for me!  Especially underwire styles, hello gaping cups!

But not Shein!  Their cups actually fit me.  They also have amazing one pieces and plus sizes for those with larger chests and more curves.

And let’s not even talk about their amazing selection of mom friendly swimwear!  

So here’s the low down on bikinis and swimsuits from Shein first hand, especially for those A cup ladies.  

Shein Swimsuit Pricing

Shein has swimsuits for around $15 or under for an entire set.  That’s both the top and bottom for $15!!  This is incredibly affordable if you are on a budget and want some cute swimsuits for your next trip.  Their one-piece swimsuits are around the same price.  Most retailers charge more for underwire bikinis, but not Shein, those are around $15 for the set as well.

Shein also sells swimsuits in separates in case you need different sizes for top and bottom.  Buying tops and bottoms separately will not cost more!

High Cut Shein Swimsuit Review

I’ve been loving high cut bikinis lately. It’s totally all the rage since the 80s and 90s are making a huge comeback.  

This high-waisted two-piece is so flattering for only $14!!  I bought it because I needed a more conservative suit for family gatherings.

Though this Shein bikini bottom still has more moderate coverage in the back, it makes your butt look amazing. 

The top is like a sports bra almost and really holds you in.  I thought it would make my small boobs look flatter but it really doesn’t. 

The thick ribbed material works to add more volume to your top so it actually enhances a smaller chest!

But because it’s so sturdy this would be a great swimsuit from Shein for those bustier ladies as well!  And it comes in soooo many colors! 

I’m also loving this high-waisted Shein swimsuit with a belt.

This Shein swimsuit definitely gets an A+ for being flattering, family/mom-friendly, and great for activities! (Or get it on Amazon here)

Skimpy High Leg Shein Bikini

If you want to be a bit more daring this leopard suit is for you (comes in tie-dye too here)! 

Of all the bikinis I bought from Shein, this one is definitely my favorite. 

The color looks amazing with a tan, the bottoms are super cheeky in the back (but not a thong bikini), and you can wear it high on the leg or on your hips.

The top of this Shein swimsuit is both functional and supportive. 

Something about the scoop on this one looks great on A cup ladies!  It scoops just a bit lower than other bikinis I’ve seen in this style, giving your girls a really flattering shape! (Get it on Amazon here.)  Solid colors are available too here.

Shein Triangle Tie Dye Bikini Review

Shein has so many tie-dye bikini options and this one and this one were both highly rated! 

But after studying the pictures and the cut I really didn’t think they would look good on someone with a smaller chest.

Instead, I went with a tie-dye Shein bikini that has a triangle top and high cut leg.

I really love the skinny straps on the bottoms and the back is super cheeky giving you a great butt.

The top has triangle cups that scrunch so you can adjust the coverage which is why I love it for smaller chests. 

Also, it’s that perfect shape for smaller busts.  Triangle bikinis that are too wide, too narrow, or too short make smaller boobs look misshapen.  

This triangle bikini from Shein has the perfect width to height ratio to flatter a smaller bust.

Unlike most triangle cups that tie at the neck, these have shoulder straps that attach to the band at the back, which I love. (Get it on Amazon here, and here)

Shein Underwire Swimsuit Review

Being an A cup I’ve always stayed away from underwire swimsuits because they never fit.  The cups are ALWAYS too big for my small boobs and gape horribly.

Shein though, being a Chinese company, seems to have to take smaller busted ladies into account when designing their underwire swimwear and for once I can wear it!

I’ve gotten so many underwire bikinis from Shein and they all fit amazingly well!

This style comes in quite a few prints and colors and I love it!

If you are bigger than a B cup you will probably not be able to wear this without a nip slip! 

shein swimwear review

The underwire doesn’t really offer support but the cups make smaller boobs look amazing! (Get it on Amazon here)

You can wear the bottoms high on the leg or straight across, and it’s cheeky in the back, my favorite style!

I absolutely love this bikini and wore it to the pool and the beach in Delaware.

This next underwire bikini from Shein is everywhere! I first saw this style a few years ago when Amanda on Summer House wore it! 

shein v wire bikini

What can I say I fell in love with the style, but she looks like at least a C cup so I really wasn’t sure how it would look on me.  (Get it on Amazon here)

But for $9 from Shein, I thought I’d give this swimsuit a try! 

shein swimsuits review haul 2021

The bottoms are the best part.  The V-cut is so flattering it’s insane how skinny they make you look!  The back is VERY cheeky so it’s definitely not a conservative bikini.  

Surprisingly the top fits and looks amazing!!  The wire on this one is super hard and doesn’t bend at all, but it still somehow looks amazing on.  If you are in A cup this Shein swimsuit will look amazing on you!  It comes in so many different colors too.

My latest underwire Shein swimsuit purchase is this one in yellow.

This Shein scrunch tie front underwire bikini is so cute and the cups are perfect for a smaller bust.  One note though, the band around the top runs huge so while the cups fit the band did not.  I had to tie it in the back instead of using the sliver clasp it comes with.

The material is ribbed which super on-trend right now.

The bottoms are a cheeky cut!   

If you like the ribbed material this one is kind of a long line underwire bikini set.  I love the deep v in the middle.  Get it on Amazon here.

Shein Triangle Bikinis Review 2021

So since first writing this blog post I’ve added a ton more Shein swimsuits to my collection!

I’ve noticed not many people review Shein triangle bikinis, so I decided to test out a few and review these Shein triangle swimsuits!

Well, the verdict is Shein triangle bikinis are amazing, especially if you have a smaller bust and want a super-sexy style!

Let’s start with this black triangle bikini from Shein that has gold ring accents.  Get it here.

shein triangle bikini review

This swimsuit is the LBD of bikinis!  It definitely runs small on top so if you are a 34B or above I would size up.  The back is basically a thong with minimal coverage.

The self-tie straps are great for tying higher up on your hips and make your legs look a mile long!

It comes in 11 COLORS.  If you are looking for a sexy bikini for the summer this one is it!


The next triangle bikini from Shein that I love is this pink and green palm print one!  Get it here.

palm print bikini

This Shein bathing suit has such fun vibrant colors for a beach vacation.

The cups on the top are larger than the black triangle bikini, but the bottoms have minimal coverage in the back and are almost a thong.

I love the thin straps on the bottoms and you can definitely hike the straps up your hips for cute pics!

Next up is Shein’s smocked triangle bikini in a sexy leopard print!  Get it here. Or get it on Amazon here.

shein leopard triangle bikini

I love smocked bikinis, they really add volume to a small chest!

Out of all the Shein triangle swimsuits in this review, this bikini top has probably the biggest cups.  But it is still super flattering on the chest because of the shirred detail.

This bathing suit comes with cheeky coverage bottoms and self-tie straps that you can hike up your hips for that high-cut leg look.

If you want a teeny weeny tiny bikini for your summer trip then this pink and purple one is for you!  Get it here.

shein bikinis for small busts

I wasn’t sure about the color scheme at first, but this itty bitty suit is perfection!

The back again is basically a thong, and the triangle cups are tiny, perfect for a small bust.

There are no self-tying straps on this bikini top, and the top straps are connected to the band in the back instead of tying around your neck.  I absolutely love this style of triangle bikini top!

Again the bottoms have a high cut leg.

This is the only bathing suit from Shein that I bought that came in an XS, so that’s the size I got.


Shein Halter Bathing Suit Review

Another super popular style of swimsuit I’ve seen in 2021  is the cross halter style that you can tie multiple ways.

Shein has a unique take on the halter bathing suit, adding a wire to the bottom of the bikini top! Get it here. Or get it here from Amazon with free shipping and returns.

shein cross halter bikini

This bikini is so sexy!!  And really makes a small chest pop because the wire forms an optical illusion of a bigger bust.

I’m telling you to get this bikini from Shein now!  You will not regret it.  It’s so unique and sexy!  The top also comes with removable straps if you need more support.

This bathing suit was a little loose on me but I just twisted the “straps” a few more times around for a tighter fit in the chest.

It also comes in multiple colors and there’s even a ribbed material version!

I am loving the color of this cross halter bikini from Shein!  This one does not have the wire but is so flattering, especially the coppery color.  Get it here.

shein halter bikini

The top has no clasp in the back and ties around your neck.  The bottoms offer moderate cheeky coverage.  Compared to some of the triangle bikini styles, this suit is definitely more family-friendly.

I’m also super stoked about this style, which has extra-long straps to tie around your waist.

And the last one of these Shein halter bikinis is this royal blue number!  Get it here. (Or get it on AMAZON here)

This fits pretty similar to the copper one above, but the bottoms have much less coverage on the back.

Not a family-friendly suit, but perfect for a vacation in Cancun!

Comes in 8 colors!

Shein Scrunch Bandeau Bikini

I actually saw a bunch of these bandeau bikinis all over the place last year.

So this year I decided to take the plunge to see how they would look on my smaller chest! Get it here. (Or on Amazon here, with free shipping and returns)

tie dye swimsuits

I picked up the tye die version so I could match it with my daughter’s mermaid swimsuit.

The top has two strings that tie in the back, or you could tie the top string around your neck.  I however did not really like how that looked.

The bottoms offer adjustable coverage because you can move the fabric around on the string.

You can totally hike the side tie string bottoms up your hips for an on-trend look!

To be totally honest, I have mixed feelings about this Shein bikini.  I’ve never been a fan of this type of bottom because I think it looks like a diaper.  But it’s so popular I had to give it a shot!

I also doubted the top would fit my small chest but it does!

The removable pads do stick out a bit so I might take them out.  It does come in a ton of colors and patterns so if you are a fan of this style you’ll have a lot to choose from!

Shein One Piece Swimsuit Review

This Shein one-piece swimsuit is amazing!

I absolutely love it and the color is great on warm skin tones. Get it here.  Or get it on Amazon here, and here, more colors here.

shein one piece review

This one-piece swimsuit from Shein has a deep v and high cut legs, very on-trend right now.

I’ve been wanting to review Shein one-piece swimsuits for a while now and I’ve had my eye on this one.

Definitely don’t regret the purchase!

This style one-piece has super long straps you basically pull to the back then wrap around your waist.  Gives you the tiniest waist!

Because of the deep v part though, it’s not super secure on top, especially if you have a large chest.

But if you are part of the itty bitty committee then you shouldn’t have a problem!

The back has cheeky coverage!

This style also comes in solid colors if you are not into animal print. Get it here.

Shein Swimsuits Quality Review

Shein has really overcome some of the quality issues I’ve seen in the past!  All the swimsuits I bought from Shein have been of decent quality for the price.  

I would say the quality of Shein swimsuits is similar to Forever 21, H&M, and Target.  Meaning the materials and sewing is similar.

But I find the cut and fit of Shein swimwear BETTER than Forever 21 or Target!  The cuts of Shein bikinis are more modern and on-trend and definitely fit better on those with a smaller chest.  H&M however usually fits me pretty well on top, but their bottoms tend to be made for those girls without curves.

I find that both Forever 21 and Target make their cups way too big for someone with an A cup and are just flat out unflattering on those that have a small chest.  You really need to be a 34B or above to shop from some of the mass retailers in the USA.

Shein Swimsuits Sizing

For each swimsuit, Shein has sizing information under the size and fit tab which gives you the size for that particular swimsuit.  Since they have thousands of swimsuits this method makes it easier to find sizing information for the exact Shein swimsuit you want to purchase.

If you hover over the size with your mouse, Shein pops up a display that shows actual swimsuit measurements as you can see below what I’ve highlighted in yellow.

shein swimsuit sizing

If you are still uncertain of your size look at Shein swimsuit reviews for each swimsuit before purchasing for sizing information.  You can sort Shein swimsuit reviews by size and color and filter for reviews that include pictures.  This is mainly how I determine what will look good on me!

Shein also sells swimsuits as separates, meaning you can buy the top and bottom pieces separately in different sizes.   

This is especially convenient if you are two different sizes for your top and bottom.  Instead of looking in “Bikini Sets,” look in “Bikini Tops” and “Bikini Bottoms” on Shein’s website to create your own swimsuit set.

Many customers complained about not being able to buy swimsuits in separate pieces because of sizing issues in the reviews I saw on Shein’s website for swimsuits, and now it looks like Shein has addressed the issue.

Shein Swimsuits Shipping & Returns

Shein offers free shipping usually on orders over $29, occasionally they will have free shipping on any item.  Shipping takes about 2 weeks, so if you want to buy it for a trip, order early!  

Though Shein has free returns for most of their clothes, they do not allow returns for swimsuits.  But at $15 per set, it’s not a huge loss if you don’t like the swimsuit.

Here’s a hack though, most of the bikinis from Shein are also available on Amazon (I’ve linked the Amazon versions above).  And Amazon usually has free 2-day shipping if you have Prime and FREE RETURNS, even on swimsuits!  

BUT you will pay about double the price on Amazon for exactly the same bikini because of the convenience factor.

My Size Info

And lastly here’s my sizing info!  I bought all the Shein swimsuits I reviewed in the smallest size available (small).  I’m a 32A, 25” waist, and 5’4” tall.
