Best Suit Ever!

Ever since I was diagnosed with melanoma, I have been searching for a bathing suit that is protective, flattering, tight-fitting, and flexible enough to allow me to swim laps several times per week - not cause drag while swimming and hold up against chlorine. So far, the bathing suit has exceeded my expectations. Thanks for making a superior bathing suit!

Thank you for sharing your experience! We’re so happy our suit provides the protection, fit, and performance you need. Wishing you many safe and comfortable swims ahead! ✨

My favorite one piece !

I ordered this one-piece swimsuit for freediving and I am delighted with it. Since I have been wearing it, I have felt much less cold during my sessions. The resistance of its materials, its sexy cut, its comfort outside and in the water, its anti-UV protection make it a simply perfect and essential accessory. I can only recommend it !

I dont tell anyone where i got this

I get asked ALL the TIME, where this flattering second skin sexy black suit is from. I GATEKEEP I admit it. I don’t tell anyone because it’s my favorite. I don’t mind telling you this because you’re not in my neighborhood or surf spot so I’m all for you looking gorgeous and twinning with me at your own spot. And you will! This suit is flattering, pulls in all the right places and forgives the spots that need movement. I surf and freedive in this suit and love how it feels in the water.
It’s thick enough to be a warm layer underwater but not a problem in Hawaii summers. Honestly it should be illegal to look this cute, I wish I could replace every flimsy crap see through suit I ever bought with the timeless pieces from this brand. (Oh wait I just did)

This is a sexy swimsuit!

Super chic and holds and lifts in all the right places. I have curves, especially around the middle and I feel really confident in this suit. Range of arm motion for ocean swimming is optimal. Highly recommend

I think this may be the best fitting swimsuit I’ve ever owned/put on my skin. It looks and feels incredible. It’s somehow modest yet sexy - I’ve literally never felt so confident!!

I am a US size 6 and I purchased the M. Definitely plan to purchase more from Ocean Soul!

FAQS

We line all our snow white surf suits with a beige econyl sustainable fabric, to prevent them from becoming transparent.

Our one piece surf suits do not have built in support. They are double lined and are a firm cut, designed to hold you in. We have customers from a AA-D that are happy with the support with our surf suits.

You can adjust the fit of each surf suit by hitching the leg high up on your hip, which gives you brief coverage. Or pull it down on your hip for more coverage.

If UPF protection is important to you, opt for the darker colours. The Sulawesi in Midnight provides the most UPF block out, due to the dark colour of the fabric and long sleeves.

All our one piece surf suits are designed to be like shape wear and hold you in. If you prefer a more relaxed feel, size up and if buying the midnight go up two sizes, as the black colour doesn't have as much stretch due to the dying process.
