About Us
The Story of ISMÊ Swim — by Isabella Bailey
I grew up on the beaches of Rio de Janeiro, where a bikini is never just a bikini. It's how you carry yourself. I could never find a suit that gave me that feeling here since I moved to the US, so I made one. ISMÊ SWIM is the result: the swimwear I always wanted, designed for the girl who wants to, first and foremost, feel good about herself. From there, she naturally stands out in the crowd
ISMÊ SWIM (also written ISME) is a textured Brazilian swimwear brand, born in Rio and based in California. We're known for elevated textured fabrics (think ribbed, terry, velvet, eyelet and shimmer) finished with gold charms, beads and hand-placed details you won't find on an average triangle top. Every style is built on the DNA of the Brazilian bikini: cheeky, flattering cuts designed to lift and flatter all body types.
We release in limited drops, so each piece stays personal, never mass-produced. In 2025, ISMÊ was featured in the Sports Illustrated Swimsuit issue, a milestone for a women-owned small business that started with one girl and a sketchbook.
Born in Brazil, made for everywhere. Welcome to ISMÊ.
Product Care & Brand Love
How do I care for my ISMÊ swimwear?
Rinse in cold water after each wear — especially after chlorine, salt water, or sunscreen contact. Hand wash gently, avoid wringing, and lay flat to dry away from direct sunlight. Don't machine wash, tumble dry, or iron. Avoid sitting on rough surfaces, which can snag the fabric.
Why does swimwear need to be rinsed right away?
Chlorine, salt, sunscreen, and oils break down swim fabric and can cause fading or loss of stretch. A quick cold rinse after each wear keeps the color and shape looking new.
Do you restock sold-out pieces?
We work in limited drops with statement details, so some pieces don't come back once they sell out. Sign up for restock alerts on the product page to be notified.
Sizing & Fit
Do ISMÊ bikinis run small?
ISMÊ Swim is designed with Brazilian cuts, so our bottoms offer cheekier, higher-cut coverage than most US brands and our tops run true slightly small. If you're used to full-coverage swimwear, the fit will feel more minimal by design. Check the measurements on each product's size guide before ordering.
How do I choose my size?
Use the size guide linked on every product page. If you have any questions, feel free to email us at contact@ismeswim.com or send a DM with your bra size, jeans size, and height for reference.
I'm between sizes — should I size up or down?
We recommend sizing up on bottoms for more coverage and staying true to size on tops. If you're unsure, email us at contact@ismeswim.com or via DM with your bra size, jeans size, and height for reference.
Are the bottoms adjustable?
Some of our bottoms feature tie sides that adjust for a custom fit; fixed-side styles are noted on the product page.
Can I exchange for a different size if it doesn't fit?
Yes. You have 15 days from delivery to start an exchange through our returns portal, as long as the piece meets our hygiene requirements (see Returns & Exchanges policy)

Returns & Exchanges
What is ISMÊ Swim's return policy?
Orders placed on ismeswim.com are eligible for exchange, store credit, or refund when requested within 15 days of delivery, as long as the item meets our hygiene requirements. Final sale items are not eligible. Please see the full Refund & Exchanges policy and requirements.
How do I start a return or exchange?
Go to our returns portal, enter your order number and email, and follow the steps to choose an exchange, store credit, or refund. You'll get return instructions and a shipping label through the portal.
How long do I have to return or exchange?
You have 15 days from the date your order is delivered to start your return or exchange in our portal and ship your item back.
The full process: request within 15 days → ship it back → we receive and inspect it → your refund, credit, or exchange is released.
How are returns evaluated?
Every return is reviewed case by case at our facility. Your refund, store credit, or exchange is only released once the item is received and passes inspection — meaning it meets all of our return requirements (unworn, tags on, hygiene liner attached, no stains, odors, or body products). Items that don't comply are rejected and returned to you at your expense.
Do you offer exchanges?
Yes. You can exchange for a different size, color, or style through the returns portal. If you want your new item faster, choose Instant Exchange at checkout in the portal and we'll ship your new piece right away.
When will I receive my exchange item?
For a regular exchange, your new item ships after your return arrives and is inspected (this protects everyone, since worn or unhygienic items can't be resold). If you choose Instant Exchange, your new item ships immediately — see below.
What if the item I want to exchange for sells out?
Our pieces come in limited drops, so an item can occasionally sell out while your return is on its way back to us. If that happens, we'll reach out with your options — a different size or style, store credit, or a refund. Choosing Instant Exchange is the best way to lock in your new piece right away.
What is Instant Exchange?
Instant Exchange lets you get your new item shipped right away instead of waiting for your return to arrive. Here's exactly how the card part works:
- When you choose it, we place a temporary hold (an authorization — not a charge) on your card for the value of the item you're returning. No money is taken; it simply verifies your card.
- You then have 15 days to ship your return back.
- Ship it back in time and it passes inspection → the hold is released and you're never charged. Your exchange is complete.
- Don't send it back by the deadline, or it comes back not in resellable condition → we charge your card for the value of the item you kept.
In short: the hold is a temporary authorization, released once your return is on its way back to us. An actual charge only happens if your original item isn't returned in acceptable condition by the deadline.
What condition do items need to be in for a return?
Because we sell swimwear, hygiene is essential. To be eligible, items must be:
- Free of any stains (no exceptions)
- Tags on
- Unworn, unwashed, and unsoiled
- Hygiene liner attached
- Free of odors, perfume, lotion, and self-tanner
- Untied and returned in the original zip-lock bag
If these conditions aren't met, the return is rejected and sent back at your expense.
Which items are final sale?
Items bought during Black Friday promotions, sale events, or at a discounted price are final sale and can't be returned, exchanged, or refunded.
How long do refunds take?
Once your return is received and inspected at our San Diego returns center, we issue your refund to your original payment method. Please allow 2–5 business days from delivery to our facility for processing; your bank may take a little longer to reflect it and ISMÊ is not responsible for delays from bank institutions.
Do I have to pay for return shipping?
If you added the "Free Returns" option (Checkout+) at checkout, your return shipping is free. If you didn't, a shipping/handling fee applies and is deducted from your refund or exchange. (See Coverage below.)
IMPORTANT: coverage makes your shipping free; it doesn't waive the cost of a kept item in an Instant Exchange if you don't send your return back
Coverage & Lost Packages
What is "Free Returns + Package Protection" at checkout?
It's an optional coverage you can add for a small fee when you check out. It unlocks free return shipping later and protects your order against loss, theft, or damage in transit. Honestly? Totally worth it. For a few extra bucks your shopping experience can be even smoother.
Is buying the coverage worth it?
If you think you might exchange or return (e.g. you're unsure about sizing) or you've had porch-theft/lost-package issues before, it's a low-cost way to protect your order and get free returns. It's completely optional but highly recommended
My tracking says delivered but I can't find my package. What do I do?
First, check around your delivery area — mailbox, front and back doors, with neighbors, and with your building's mailroom or concierge. Carriers sometimes leave packages in hidden spots. If you added Package Protection at checkout, you can file a claim (see below). If you didn't, ISMÊ Swim isn't responsible for packages once the carrier marks them delivered, but you can contact the carrier directly with your tracking number.
How do I file a claim for a lost, stolen, or damaged package?
If you added Package Protection, file a claim at resolve.seel.com using your order number and email (the link is also in your order confirmation email). Choose what happened, select the item(s), and upload any supporting documents. Theft and damage must be reported within 7 days of the package being marked delivered; all issues within 90 days of the order date.
