Customers say these bikini bottoms feel like seamless underwear and provide excellent comfort without digging in. They appreciate the flattering V-cut design and high-waisted style that offers good coverage while remaining sexy. Many mention the bottoms stay in place well and don't ride up during activities. The fabric feels high-quality and soft against skin. Common feedback includes sizing running large, with many customers needing to size down from their usual size. Several note the bottoms stretch significantly when wet, requiring a snugger initial fit. Users praise the wide waistband and grip lining that prevents rolling. Some mention wanting more color options available.

Swimsuit care

Hand wash in cold water as soon as you can after use (rinsing in the shower is fine!)
DO NOT machine wash.
Lay flat to dry, do not hang.
Do not dry clean, iron, or machine dry (even on a delicate cycle...) as this can, and most likely will, damage your onewith.
Hot tubs and chlorinated pools with harsh chemicals can impact the quality and longevity of any swimwear, so it’s best to avoid them if you want to keep your swim in tip-top shape.
If you wear your onewith under normal clothes, keep in mind that friction can create pilling/snagging. We prefer to wear our onewith under beach cover-ups/sarongs, which are created to be worn with swim.
Sunless tanners, suntan lotions, oils, and harsh chemicals can ruin your onewith - ensure to not get these products in contact with any swim/garments!

Perffff!
These fit in all the right ways! I’m 5’0” 123lbs and got the medium. As long as you stretch it a little like the directions say, it forms perfectly to your body!

frequently asked questions

does that strip inside your suits contain latex?

onewith can not guarantee that the inner grip strip inside of our suits does not contain trace amounts of latex. Therefore, if you have a latex or adhesive sensitivity/allergy, we recommend you exercising the same caution and sensibilities you would take in general when determining whether or not to use or wear a product that may contain latex or adhesive, should you have a known issue with these substances.

what size am I?

in general we are true-to-size. we have a handy-dandy size quiz on every product page. take it once and it will give you your best size for each & every style!
you can also reference our size guide here. there are fit notes on every product page to help you choose your best size!

where are your suits designed & made, and what kind of fabric is it?

we are a US-based company; our suits are designed in North America and made in China. all pieces are made of 80% nylon, 20% elastane.

are your suits see-through?

our suits are 2 layers of fabric just like any other swimwear...it's just bonded, not sewn with tight seams, so that it lays flat on your skin like your favorite no-show underwear. with that, onewith is the same opacity as all other swimwear. if you are sensitive to ANY sheerness when wet, as with ALL swim, opt for a darker color.

when are you restocking?

sign up for restock notifications on the product pages of the item you want, and be sure to follow us on Instagram for the latest & greatest of all things onewith!

are your suits thin? like, will they cause 🐫toe?

our suits are 2 layers of fabric just like any other swimwear; it's just bonded, not sewn with tight seams. so while it may appear to be thinner, it is actually the same thickness of material as most traditional swim. so if you're worried about a case of 🐫toe, while we can't guarantee our suits are frontal-wedgie-free, so-to-speak as every person's body is different...we can say that there is no reason why our suits would cause it more than any other swimwear. if you're ever worried about anything showing through, a general swim tip is to opt for a darker color or a suit in a pattern.

why don't you have more colors/styles?

we design by demand and data. if we get enough requests for something & it stands to reason it might do well, we might just make it! for new color requests, please watch this video for more info on why we don't make a lot of colors.

if I don't know my size, can I just order multiple sizes and return what doesn't work?

⛔ we strongly discourage bracketing (ordering multiple sizes or styles with the intention of returning what doesn't work) as well as high-quantity first orders. while we completely understand the desire to find your perfect fit, this practice creates real inventory challenges for us as a small business, and also compromises hygiene best practices.

we're big believers in conscious consumerism and encourage small, mindful first orders. once you've found your perfect size and your new favorite swim, we absolutely love it when you stock up — just please do so with the intention of keeping your order, not returning the extras. we know this kind of large-order flexibility may feel standard with bigger retailers, but we ask that you consider how bracketing and high-volume returns affect a small business, its customers, and the environment.

returns of 4 or more items per order will be subject to a $15.95 processing fee in addition to the standard return fee.

what size am I?

in general we are true-to-size. please reference our size guide here. also, TAKE THE SIZE QUIZ! it is so helpful, we made sure of it :)

what happens if my swimsuit doesn't fit? can I return/exchage?

we offer a 14-day return/exchange policy on all swimwear, beginning the day of carrier-confirmed delivery. a customer's first exchange is free to ensure you find your perfect onewith fit. returns for store credit are also free; returns for a refund incur a $12.95 fee (additional fees apply for high-volume returns). all returns and exchanges must come back in original, unworn condition with the hygiene liner intact. Read more about the onewith return policy here.

in general our suits run true-to-size, but be sure to take the size quiz linked on each product page. the quiz is tailored to each style, so you'll always get the most accurate recommendation.

⚠️ NOTE: ITEMS MARKED FINAL SALE + INTERNATIONAL ORDERS ARE ABSOLUTELY, POSITIVELY FINAL SALE. no returns, no exchanges, no exceptions.

i wear [this] bra size. what size top am i?

because we make swimwear that feels like underwear, our swim tends to be a great fit on so many bust sizes... from AA to J cup and beyond! check the product images to see our tops on a range of bust sizes. check out this blog post for a comprehensive guide on how to best pick your top size. pro-tip for choosing your onewith bikini top size: we don't size by cup! we'd recommend going with the same size top you would for a camisole.

Can I see a certain style on a body type similar to mine?

we offer lots of content of our swim on different bodies all over our site + socials! Namely, we have a onewith wearer gallery all of our product pages, our ‘plus size’, ‘try-ons’, ‘customers’, and fuller bust’ highlights on Instagram, the coverage/support meter on product pages,, size guide page, and more! we have so much content with lots of different representation.

do you ship internationally?

onewith is proud to offer international shipping!
