The suits are fine, (not worth $130 per set) but they advertised free shipping with orders over $100. Shipping was still $20 for standard delivery which is insane. My order took over 3 weeks to arrive... See more

I love these swimsuits. They fit the best! However I have to share my annoyances on shipment times. They always take over 2, sometimes 3 weeks to ship out the product. A little long IMO... but it's wo... See more

Horrific. Don’t waste your time and money.

Omg just don’t. I ordered a few bikinis on March 14 and it took more than 3 weeks to ship even though their website says shipping in the US is under 2 weeks. Also it shipped from Colombia so I didn’t receive my order until about a month after I ordered it. The customer service phone number listed on their website goes straight to voicemail most of the time. Other times, it rings and rings until it goes to voicemail and their voicemail box is full.

I measured myself before ordering to ensure sizing. I ordered everything in a size medium but the sizing of the items I received was so inconsistent. Two of the top were TINY. The other top was too big. So I emailed them to start the refund process.

I had to send at least 3 emails to get any response. I was very specific about wanting to return my items for a full refund, but the person who finally responded weeks later said they were forwarding my email to someone else to start the EXCHANGE process. I never said I wanted to exchange anything.

I had to email them 3 more times and I got another response saying they were having issues with creating shipping labels for returns and would have a label to me by the end of the week. It is now the end of the week and I still haven’t heard from them.

Over the course of the last 2 months I have sent countless emails and I still don’t have any instructions on how to get a refund. Please don’t waste your time. Customer service is nonexistent.

Read The Reviews - Negative is closer to reality

Wish I had found these reviews. The frustrations begin with the shipping, and continues through the product sizing, product quality, and return/customer service. From time of order to delivery was well over 3 weeks. The quality of the swim suits was FAIR, but does not constitute the pricetag. The sizing is wholly inaccurate, as a 32-34 A Cup bust, there should be NO reason I cannot fit into a "Medium" swim top. Separately, the customer service to return is limited only to email. And return requests are met with an ambiguous feedback survey and then "the system is down" I should have my return label within a week?!?!? I've already been out over $250 on this swimwear for almost two months, and I cannot use this product. Its a shame because the styles were cute in concept.

My wife exchanged a top I got for her

Edit: The team expediated the shipping to get this out in time for our trip.

My wife exchanged a top I got for her. The new one never came. I guess we'll need to visit a topless beach to get any use out of this.

No communication, Never ship items

I made two orders to this company and after 22 days I still hadn’t received an email confirmation saying they had shipped either item. When I opened up the order page it was consistently listed as “Processing”. I emailed the companies customer service and 5 days later—-still no response. I then attempted to DM their business on instagram, still no response. I ALSO attempted to call them during business hours and I got message saying their voicemail box was full!! Super sketchy, I ended up calling my bank and disputing the charges because this is ridiculous. I highly recommend avoiding purchasing anything from this company, you don’t know whether or not you’ll ever get your items and they won’t respond to any attempts at contact, so it’s definitely a gamble. Very disappointed, but hoping to protect future buyers from wasting money and getting frustrated.

1+ month after placing order and it has not been shipped

I ordered from this company a few years ago. I liked the design and colors of the swimsuits and they are very comfortable. However, they eventually get discolored and the straps get wrinkles.

I decided to order a few new swimsuits from this company on 3/14/2026. It is currently 4/16/2026 (over a month since I ordered) and the company has still not shipped my order. I contacted them many times asking when my order will be shipped. They first said 5-10 business days and that the swimsuits are made to order. The company does not communicate that when you are ordering and I do not remember it being that way when I ordered years ago. 10 business days passed by and my order still hadn't been shipped. They then told me my order would be shipped the following week, but it was not. All my attempts to contact the company since then have been ignored. My credit card was charged on 3/14/2026 for this order even though the order has not been shipped and may never be sent to me. I don't know what is going on with this company but buyer beware.

I have attempted to contact the company through email, the oneone swim website, X, and instagram.

Very disappointing customer service…

Very disappointing customer service experience with OneOne Swimmingwear.

Unfortunately, I had a very bad experience with this company. I ordered a swimsuit that was on sale, but they sent me the wrong size. I tried multiple times to contact their customer service to resolve the issue, and they never responded or offered any real help. The only response I received was that the item was a “final sale” because it was purchased during a promotion.

Regardless of a sale, sending the wrong size is clearly the company's mistake, and it should have been addressed.

Although the quality of the swimsuits seems good, I would not recommend buying directly from them due to their extremely poor customer service. Additionally, the exact same designs can be found on other websites for much lower prices.

Overall, a very frustrating and disappointing experience.

I placed an order in MARCH OF 2025

I placed an order in MARCH OF 2025. As per policy, i sent back a few items for refund, within the 30 day window. I received an email that they received my return and a refund would be issues in 30 days. This was 10 MONTHS AGO. I have received 2 emails in the past 10 months simply stating there are delays with my refund " due to external circumstances." New arrivals are posted daily on instagram, so the business still exists. Whatever these circumstances are has nothing to do with me. I am extremely dissatisfied and this is rising to the level of fraud that there is email confirmation that i will received my refund and after 10 months they still have not. Needless to say, i WILL BE REPORTING THIS COMPANY

Will never ever be ordering from ONE ONE again!

Will never ever be ordering from this horrible company again. Extremely slow shipping, false advertisement of swimsuits (I ordered tops that were advertised to come with padding and they arrived without padding) ,and they refuse to right their wrongs! If you are considering ordering from them, DO NOT!

I am extremely disappointed with the customer service. I emailed them several days before my order was shipped. It had been almost 3 weeks since the order was placed and it would not arrive on time for my trip. I asked them to cancel and refund the order. They were pushy and tried to have it shipped to my vacation spot instead, but it’s a short weekend getaway and would not get to the resort in time either. I repeatedly asked for a refund and every response they sent was a “well we can try to get it there”. Finally they said the order was shipped and it won’t arrive until after my trip is OVER and their return policy doesn’t allow for items that were on sale to be returned!!!!! So now despite being asked to cancel my order 3-4 times, they shipped it anyways knowing I won’t be able to get a refund.

An awful experience with this company

An awful experience with this company. I ordered a swim suit as a Christmas present on December 4th. As of December 10th the order still showed processing, so I tried to call the number on the website only to get a message that the voicemail for this phone was full, so I emailed the support email to make sure everything was ok with the order. The next day I received a canned email explaining that it can take 5-10 days for orders to process and ship. I then waited until 11 days had passed and emailed again as to the status of the order. 2 days later received the same canned email as before. It has now been 18 DAYS since I placed the order and it still had not shipped. I then sent a 3rd email. It is quite ridiculous to order pre-produced product on Dec 4, and not be able to get it in time for Christmas. The swim suit finally came after Christmas 12/29/25. It didnt come close to fitting based on sizing provided on website. (My daughter has purchased many swim suits about 2-3 a year and she knows her size very well.) Contacted oneoneswim support via email only to receive an email back saying that because the swim suit we purchased was on sale or reduced by 30% or more they do not allow any returns OR EXCHANGES. They wont even exchange the suit. Absolutely atrocious company.

Would give less stars and a huge ‼️🚨DO NOT BUY🚨‼️ if I could.

Ordered back in August didn’t receive a package or warning about delay so in mid September I emailed “support” to cancel. The said it would be 30 business days to be sent to billing it’s now almost Christmas and I still have not received anything. It’s giving scam you guys!!! Do NOT ORDER FROM ONE One SWIM!!!!!!‼️‼️‼️🚨🚨🚨 huge scam. The reviews for 5 stars are also anonymously posted and sketchy save your money and go somewhere else.

Super slow processing and shipping

If you're in no rush to receive your order than it's great. It took over a month for my order to even process and over two months for me to receive it. Order at your own risk but if you're looking to have it in time for an event sooner than 2 months out, I'd shop elsewhere.
