ONEONE SWIM Avis 

I ordered swimsuits from ONEONE during their Black Friday Sale and apart from taking three weeks to arrive, the tops did not fit (too small despite following the size chart and ordering my usual size). When I emailed the company for a return, they responded that items 30% and over are final sale. This information was hidden in fine print and not clearly stated. I feel disappointed and deceived by the company.

Beware of the return policy and read the fine print. We purchased items on sale and did not realize they were final sale b/c it did not say it anywhere when we were buying or checking out. Only did I see the fine print when we needed to return. Horrible customer service when discussing our issue and still not held accountable for deceptive practices.

Oneone has been my go to swimsuit brand ever since I found them. They are reliable and cute. I always find myself reaching for a Oneone suit when I have the chance. Genuinely my favorite brand and couldn’t recommend it more!

I am loving this brand so much, each piece is special, they are beautiful, I love the designs and colors!

The fit, the colors, the comfyness its just stunning✨

Absolutely love these bikinis! They’re incredibly flattering, and I get compliments every time I wear them. As someone who’s quite tall, it’s always been a challenge to find swimwear that fits well and accentuates my body. One Swim has nailed it—I’m so glad I discovered them! They’ll definitely be my go-to from now on.

I bought several swimsuits from here. When I checked, 1 of the 4 swimsuit I purchased said "Final Sale". When I contacted them to return 2 of the other swimsuit, they told me none of my purchases could be refunded. There was some fine print under their returns policy that I guess said any discounted item couldn't be returned. Very misleading because when check out, this did not seem like the case.

Really disappointed by their exchange/refund policy. I purchased two bathing suits as part of a Black Friday sale November 2024. The fits for both bikini tops and bottoms were way too tight and not flattering on my curvy shape, and so I emailed their customer service about returning and I was told "After reviewing your order, we noticed that all your items have a 50% discount. Therefore, they are not eligible for exchange or refund." This was in no way made clear on the website page when scrolling through and clicking on items, on the order confirmation page, or in the email confirmation I received. I think these are very strict terms that are very well hidden on the website. So, learn from my mistake and please review oneone's refund/exchange policies before purchasing!!

I ordered two swimsuits on Dec. 2, and 3 days later I received a notice that the shipping label was printed. It has been 5 more days and the package has not been shipped. I have attempted to reach out to support 4 times by email and 6 times by phone, in addition to contacting them on their listed WhatsApp chat line. I have not been able to reach anyone. My trip that I ordered the suits for starts in 2 days and I think at this point I have to initiate a chargeback on my credit card.

I cannot imagine that all the positive reviews shown here are not spam. I checked them before ordering and proceeded based on the number of positive experiences listed. Now I know that was a mistake. AVOID AT ALL COSTS!

The swimsuits are the perfect Fit for any type of body. The fabric has the best quality and the colors stay the same through time. I just love them !

I bought a swimsuit for 50%. The return policy said they accept returns within 30 days... except if you scroll to the very bottom there is tiny print about not accepting sale items. At this point, the entire website is on sale. I tried to contact their customer service. The number doesn't work and the email is run by someone in South America who does not give a F***. This company is shady, boreline scammy. The swimwear is way overpriced. I'd say it's only worth 25% of the MSRP.

I returned items over 4 months ago, totaling $513.25 and have yet to receive a refund. I’ve contacted them several time over the last for months only to have them say that they are behind and I should expect my refund soon. I’m now out $500+. DO NOT BUY FROM THEM.

I love the bikinis from ONEONE! They are constantly releasing new designs which is nice for someone who is constantly at the beach living in swimwear. They fit great and run true to size. The material is fantastic and lasts. Whether you just want to look cute at a pool party, you’re scuba diving, or just playing hard at the beach with the kiddos these suits hold up and look cute in all scenarios!

I’m obsessed with their bikinis! They are so cute and they fit SO well. I have purchased from their website a few times and they have great customer service. I highly recommend ☺️

My all time favorite swimsuit brand! Such high quality bikinis and they fit like a dream! I’m obsessed :)

Best bikinis alive. Have never looked better!!!! All of my friends have purchased after seeing. I had an issue with a suit, just a freak one time random rip and the company took care of it right away and sent me a new one which made me love them even more!!

Love the brand, greatest quality!

Never received my refund for a return. It has been over 3 months since the item has been returned and received.

DO NOT ORDER FROM THIS COMPANY. I ordered two swimsuits over the summer and needed to return one ($75+). I requested a refund in JULY and still have not received it and it is now October 28. I have emailed 4 times and they continue to give me the run around. HORRIBLE CUSTOMER SERVICE. AVOID AT ALL COSTS.
