⛔ bracketing + high-quantity first orders are STRONGLY discouraged: while we understand the desire to find your best size(s) and styles, ordering multiple variants of a piece with the intention of returning those that do not fit/suit you creates inventory issues for us as a small business, and also compromises hygiene best practices. we encourage conscious consumerism by way of small, mindful first orders. while we naturally love when you stock up on your fave swim once you know your best onewith size, please do so mindfully for our other customers' sake (that is, without the intention of returning extra sizes/styles). while this may be more permissible for an enterprise-level company, we ask that you consider how bracketing + large returns affect a small business, its customers, and the environment. returns of 4 or more pieces/customer will be subject to a processing fee of $15.95 in addition to the return fee.

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 :)

we offer a 14-day return/exchange policy on our swimwear. the 14-day window begins the day of carrier-confirmed delivery. A customer's first exchange is FREE so they can ensure they find their perfect onewith size. returns incur an $12.95 fee to cover shipping. returns and exchanges MUST come back to us in their original, unworn condition. read more about the onewith Return Policy here.

in general we are true-to-size. but please reference our size guide here.

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

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.

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.

onewith is proud to offer international shipping!

all international sales are positively FINAL. no returns or exchanges are available for international orders.

shipping rate to your country is calculated at checkout, and is set by the carrier. in most cases, this rate also includes duties/customs! ☺️ some exclusions may apply.

it's possible you only included a phone number for contact info when you placed your order. in this case, all order updates would be sent via text. if you're not able to find any order notifications via text, please check any other email addresses you have access to. if you're still not able to find the confirmation, please send an email to info@onewithswim.com and our team will be happy to assist you!

swim is an intimate garment, and therefore highly subjective and personal. for that reason, we believe it's only right to offer returns/exchanges for domestic orders on non-final sale items. however, your return/exchange must abide by the conditions outlined.

international orders are ALWAYS final sale.
