Here's the thing: I'm all for a free-the-nip moment. But when I'm getting out of the pool, the last thing I want is to realize my once-opaque swimsuit is now actually...completely see-through. Agreed?? And if you have your heart set on wearing a white swimsuit this summer, you miiiight be concerned about choosing a suit that turns see-through the minute it hits the water. That's why I combed through thousands of reviews to find you the best white swimsuits for any occasion, from your bachelorette party to your honeymoon to your next beach vacation—and all of 'em are 100 percent nontransparent, trust.
I know shopping for that perfect swimsuit is NOT easy. You have to find the right fit, the right amount of coverage, the right material...and with white bathing suits, you've gotta take the potential for transparency into account as well. The best white swimwear options tend to be thick, padded, and lined for coverage—and if you're not looking to drop more than $100 on a bridal swimsuit you may only wear once, I've got plenty of affordable white bikinis and one-pieces that work whether you're saying "I do" or just trying to live your best vacay life. Here's a lil peek at my faves.

You might be a lil skeptical about ordering an all-white suit from Amazon, but hundreds of happy reviewers swear that this one is a worthy investment. Testers <3 the soft, ribbed fabric and unique one-shoulder silhouette with its sexy midriff cut-out—and best of all, this one won't cost you more than $50.
- Size range: S-2X
- Materials: 92% polyester, 8% spandex
Glowing Customer Review: "I first ordered this style in the Beach Riot black-and-white version, and the top had absolutely no liner so your nipples peak through. This is the exact same quality—if not better fit—and [it has] lined cups, making the top look way better on! Love it!"
You can't go wrong with a classic triangle bikini, and this one really delivers (especially considering it's a mere $24 for a full set). The two-piece is fully adjustable with a subtle ribbed texture and removable push-up padding, and reviewers are SO impressed with the quality for the price.
- Size range: XS-XL
- Materials: 82% polyester, 18% spandex
Glowing Customer Review: "Love this bathing suit. Very cute and fits right! I was concerned it would be thin and see-through, but this is not the case."
Yep, it's the internet-famous one-shoulder swimsuit that legit looks good on everyone. Thanks to the diagonal seaming and thick, compressive fabric, this one-piece (which offers full coverage, even in all-white, and light support for busts of all sizes) will make you feel like your best self on the beach.

The plunge neckline! The compressive fabric! The full seat coverage! This Andie one-piece has racked up more than a thousand rave reviews for its incredible quality and design, which allows you to feel both sexy and covered—and if you're not into the ribbed fabric, it's also available in a flat white option (as well as a long torso fit!).

Glowing Customer Review: "Love the fit, style, and feel! An amazing white suit that offers complete coverage both in and out of the water!"
It's giving ~bride-to-be.~ Beach Riot's beloved Highway Bottom got a cute makeover with this bridal version, featuring the same cheeky back coverage and compressive high waist with a pretty oversized bow on the butt (which is fully detachable, btw). Pair it with the Camilla Top if you wanna complete the lewk.
- Size range: XS-XL
- Material: 82% polyester, 18% spandex
Glowing Customer Review: "Wore this for my bachelorette party on a boat and got so many compliments! The bow is easy is remove, and the white is lined and not see-through. Definitely recommend if you are a bride-to-be!"
Why has this one-piece earned nearly 6,000 five-star reviews, you ask? Probs because it works like magic to hug you in all the right places, thanks to the adjustable straps and drawstring sides. Reviewers also rave about the ruched detailing, cheeky back coverage, and double lining, which keeps this one from ever looking sheer (even when wet!).
- Size range: S-3X
- Materials: 82% nylon, 18% spandex
Glowing Customer Review: "I was shocked by how much I loved this suit! I ordered three others that were similar and returned them. This one fit beautifully and wasn’t sheer at all! Most white suits tend to have a sheerness to them. I might get it in other colors, too."
For something a bit different, pls turn your attention to this crocheted beaut. You'll love the bandeau silhouette, beading details, and adjustable corset ties (which can be worn either in the front or the back, fyi!). And for a matching moment, you can wear it with the precious Tamarindo Ruffle Bikini Bottom.

- Materials: 95% nylon, 5% elastane
Glowing Customer Review: "The Bone Crochet material is stunning in person, and the beads add such a unique flair to the top. I've worn this as a bathing suit but also as a bandeau top, and it's easily become one of my favorite Montce items purchases. Highly recommend!"
Obsessed doesn't begin to describe how I feel about this cheeky cut-out one-piece. It's thick, soft, and has *just* enough compression to make you feel pulled together without any discomfort—and the asymmetrical design is srsly cool. Plus, the lining and removable pads will prevent any nipple peekaboos.

- Materials: 85% recycled nylon, 15% spandex
Glowing Customer Review: "I have been looking at this bathing suit for a while and finally pulled the plug and bought it. The material is incredibly comfortable and fits snug—exactly like you’d want. It also is not see-through at all, which I know is a common concern with white bathing suits."
Got big boobs? You may need a swimsuit with underwire support, like this demi-cup bikini top, which is made with compressive crinkle fabric that stretches with your body and is lined for extra support. Other perks include the extra-thick shoulder straps (which are fully adjustable) and comfy G-hook closure in the back. And for a matching set, you can add on the Always Fits Good Waist Bikini Bottom.

If you want to have a soft girl moment, this suit is IT. Reviewers love the deep V-neck top with its ruffle flounce hemline, and it pairs so nicely with the high-waisted ruched bottoms, which offer fuller butt coverage for those who'd rather not show a ton of cheek. Plus, it has removable padded cups and princess darts for added support.
- Size range: XXS-2X
- Materials: 82% nylon, 18% spandex
Glowing Customer Review: "I love that this goes well above my belly button. It’s also a bit cheeky but not too much. I like that it doesn’t cover the rear completely and makes me feel good about my body. The top fit amazing. I feel like it give great support without being heavy and thick. Oh, and the white is not see-through!"
Underwire swimsuits aren't just for those with bigger boobs, and this textured crinkle knit 'kini is proof.

Glowing Customer Review: "I ordered this top for my bach and was shook by how good I looked. I don't have a ton to work with, but this bikini top made me look and feel amazing. The best part was how secure I felt in it. 10/10 would recommend."
Found: the white monokini of your dreams. Reviewers say this cut-out stunner look ah-mazing on a wide range of body types, thanks to the adjustable shoulder and back straps and soft, stretchy fabric.

It’s thick, cinches my waist, and fits perfectly. I highly recommend this swimsuit. Got it in white and it’s not see-through."
This jacquard suit is a showstopper, no? Double-layered with light removable padding, the Santorini top is SO high-quality, and it even comes with soft underwire and an adjustable lace-up back to help you feel 100 percent supported. Make sure you get the Santorini High Waist Bikini Bottom as well!!
- Size range: XS-2X
- Materials: 80% polyester, 20% spandex
Glowing Customer Review: "This top is stunning. The material is thick, so you don't have to worry about it being see-through. I love the pattern!"
For a retro look, try this polka-dot mesh one-piece, which boasts adjustable spaghetti straps and a sexy V-neck situation. And while it doesn't offer the *best* bust support, since it doesn't have any underwire, it does have removable cups for keeping everything smooth 'n' secure up top.
- Size range: S-2X
- Materials: 82% nylon, 18% spandex
Glowing Customer Review: "I love this bathing suit! I bought it for my bachelorette party at the beach, and it’s so cute! I haven’t worn one-pieces since I was a kid, but I wanted the extra support around the tummy. This adds a bit of compression but doesn’t look matronly, like many one-pieces. It was a bit hard to get over my hips, but once I did, it hugged me perfectly!"
Yep, you've probably seen this suit all over IG, and let me tell ya, it really does live up to the hype. Made with thick, double-lined compression material, this sleek suit (which comes in two lengths) features a low V-neck front, thick cross-back straps, and a cheeky scrunch butt that'll really show off your ~best assets.~

Glowing Customer Review: "This suit has been on my wish list for a while and I am so glad that I finally purchased it! It is so soft and so comfy. I love the little bit of sideboob exposure, and the ruching makes my butt look fantastic. I feel so sexy in this suit and cannot wait to wear it for my bachelorette and honeymoon!"
A two-piece bikini and matching sarong for less than $30?? No, you're not dreaming. Super stretchy and thick, this three-piece set includes a strapless ring-linked bandeau top, cheeky high-cut bikini bottoms, and a matching side-tie coverup skirt that truly demands an IG moment.
- Size range: XS-XL
- Materials: 82% polyester, 18% elastane
Glowing Customer Review: "Material is NOT cheap looking or feeling. It’s a great bathing suit set. The top stays up and I got so many compliments on it!"
How do you care for a white swimsuit?
Every bathing suit will come with its own care instructions, but generally speaking, the best way to wash a white swimsuit is to hand wash it in cold water with a mild soap or detergent and then line dry. Side note: You never want to put your swimsuit in the dryer, as this can compromise the stretch and color of your suit.
If you notice that your white bathing suit starts to take on a yellow cast (it happens!), you can use a baking soda solution to reverse it. Try dissolving half a cup of baking soda in a gallon of cold water, then allowing your suit to soak for one to two hours. And for the sake of your suit, pls stay far away from the bleach, which can weaken swimsuit fibers.
Do you have to wear a white swimsuit for your bachelorette?
A bride-to-be may opt to wear white throughout a bachelorette weekend to stand out from the other attendees, but let's set the record straight: You definitely don't have to wear white to your bachelorette party, especially if the idea of white bridal swimwear makes you uncomfy. If your bach includes water activities, you should wear the bathing suit that makes you feel like your best, most confident self—it's your celebration, after all!!
