Do you know what time it is? Get ready for my most-anticipated post of the year: reviews of the best one piece swimsuits on Amazon. For the past several years, all of my best-selling items have been swimsuits, and honestly, it makes so much sense. The ones I share are affordable, good quality, and can arrive on your doorstep with two day Prime Shipping. What else could you want?!!

This year’s one piece suits are all under $35 with many under $30 and all have great reviews. As always, I’ve mainly stuck to my tried-and-true brands. Of course I had to try a couple newbies, but you’ll mostly see brands that I’ve personally kept and have worn for years now! Once you’re done here, be sure to also check out my 2021 Amazon one piece swimsuit reviews and 2020 one piece Amazon suits for even more of my favs!

Best One Piece Swimsuits on Amazon

My Sizing

For reference, I’m 5’7 1/2″ with a short torso and very long legs! I typically wear a 29 in jeans or a size 8. My bra size is a 36C, and I typically wear a size medium (or 8) top. 

If you ever have any question about what size I’m wearing, check the links below each image! I list any recommendations I have for sizing up or down for quick reference. (TTS= true to size!) For full details, I’ll be chatting all about quality, style, and fit in the paragraphs above each photo. Let’s go!

V-Neck Ruffle Swimsuit

You just can’t go wrong with a classic black suit. This one is adorable with a small ruffle detail at the shoulder, deep v that’s not too revealing, and sheer waist panel. As someone who doesn’t have a super well-defined waist, I love details like this panel that help create the allusion of more curves. It feels very supportive and has built-in cups. This suit only comes in sizes large through 4X. I’m in the large, and it fits more like a medium. I’d suggest sizing up one.

Tie Shoulder Ruched One Piece

Hello, adorable retro vibes! I was so pleasantly surprised when I put this on! I love that the adjustable shoulder ties can fit a variety of torso lengths. And I also love a good tummy ruching detail. It comes in 12 different color options. (This is the blue gray!) Included bra pads are removable and booty coverage is full. I sized up one to a large but would prefer a medium. Stick with your true size!

One Shoulder Shirred Suit

This is one of my favorites! I love the one shoulder detail and it has the shirring across the tummy as well! But the show-stopper is the back. It has a mid-back cut-out that connects to the asymmetrical strap. It comes in 18 different color ways, including solids and other prints! There is a shelf bra with built-in cups. I sized up one to a 10 but could have stuck with an 8. It fits TTS.

Side Cut-Out Swimsuit

I’ve always struggled some with side cut-out suits. I love the way they look but they never seem to hit me at the perfect spot. Maybe short-waisted probs? But this one has a diagonal waist seaming that seems to hit perfectly right below my bust and my natural waist. The leg is also a little higher cut, which I love! The fabric is ribbed, and it has built-in cups. Comes in two other color options! I sized up one and like the fit!

Wrap Plunge One Piece

Um, hello, va-va-voom! This is the deepest plunge suit I’ve tried, and honestly, I don’t hate it! It comes with two long straps that you halter and then wrap around the waist and tie. I wouldn’t say it’s the most mom-friendly suit, simply because the straps don’t allow for a super-secure fit at the bust. It’s also the most cheeky of the bunch. But if you’re headed on an adults-only vacay, this is the ultimate one piece!! I sized up one and like the fit.

Ruffle V-Neck Swimsuit

This one is such a sweet, feminine suit! I adore the blue color and the all-over navy and white floral print. It has small shoulder ruffles, a v-neck, and full booty coverage. I sized up one but could have stayed true to size. It also comes in four solid color options.

One Shoulder Ruffle Swimsuit

I actually shared this suit a few years back and didn’t end up keeping it. Let’s just say I had some regrets… all the way back from 2019. 😂 So here she is again, this time in hot pink! I love the one shoulder and ruffle detail. It also has ruching through the body. It comes in 45(!!!!) color and print options, so you’ll surely find one that fits your style! It’s supportive, comfortable, and yes, FULL BOOTY COVERAGE! Woo! I’d recommend sizing up one!

Ruffle One Piece Swimsuit

It’s no secret that I love a ruffle! And this one has ruffles all the way around! So flirty and fun, no?! Although the neckline is a plunge, the strap helps it feel more supportive. Cups are removable and booty coverage is moderate/very slightly cheeky. If you don’t love a bold print, this one comes in close to 25 options, including solids! I sized up one but would prefer my true size.
