Alt Swim Promo Codes & Verified Deals – October 2026

Obsessed with my new gold hardware!

Okay so who else is totally in love with Alt Swim?! I snagged one of their mesh beach skirts with the gold hardware and it's seriously stunning. The quality is amazing, and it feels so much more expensive than it was, especially with a discount code I found! Already planning my next order, probably some more gold hardware swimwear! Definitely tell your friends!

loving my new metallic bikini!

grabbed one of their metallic bikinis, the underwire bikini top is super supportive and looks amazing! so happy with the fit, i'm definitely going to shop here again and tell all my friends. i even got a great deal with a code at checkout, tho you can only use one.

Good quality, but shipping is a pain

Used a 20% off code on my recent order for another one of their triangle bikini tops. The quality is consistently good, comparable to Sommer Swim, and I appreciate their sustainable swimwear efforts. However, tracking my Alt Swim delivery was a bit of a maze this time, which was frustrating since I've ordered from them before and it's usually smoother.

Worth the investment for quality

I was looking for a good quality bikini that would last, and the prices here were a bit higher than I usually spend. I went for a bandeau top and high waisted bottoms. I signed up for the newsletter and got that first order discount, which definitely helped make the purchase feel more justifiable. The materials are really nice; it doesn't feel flimsy at all. Shipping took about a week and a half. I think it was worth the money for the quality I received, especially with the discount.

Cute bikini, loved it!

Got a floral swimwear set for my vacation and it was super cute. It fit really well, which I was happy about. Delivery was fine, got it in about a week and a half. No drama. Just a nice bikini.

Good quality, delivery a bit slow

I ordered a personalized one piece for my honeymoon and it arrived well-packaged. The material felt really high quality, especially the gold hardware. The personalization was exactly as I wanted, which was a nice touch. My only complaint was that shipping to the US took about 10 days, which felt a little long. I had to follow up with customer service once, and they were helpful. Overall, I'm satisfied with the product's value, but the delivery could be quicker.

Always reliable, great swimwear

This was my third purchase from Alt Swim, this time I bought a linen shirt for resortwear. Their quality is consistently good. My previous purchases, a few bikinis, have held up really well over time. This shirt was no exception, the fabric is soft and breathable. Delivery was actually a bit faster this time, reaching me in about a week. It's why I keep coming back; I know what I'm getting, and it's always solid.

Quick delivery, good fit.

Ordered a string bikini. Arrived in 9 days. Fit as expected. Quality seems good. Happy with purchase.

My first Alt Swim experience

I decided to try Alt Swim after seeing a friend's bikini. I ordered a ribbed fabric bikini – a triangle top and cheeky bottoms. The ordering process was straightforward on their website, no real issues there. Shipping to California took about 8 business days, which is reasonable for international. The quality of the fabric was impressive, very soft and felt durable. Sizing was true to what their chart suggested, which is always a relief with online swimwear. I did have a question about care instructions, so I used their online chat. The response was quick and clear. The stitching looked solid, and it held up well after a few washes. It's definitely a step up from cheaper brands I've tried.
