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

Surfer girl

This is such a good suit for my daughter. Amazing quality. It is one of her faves. We love it.

MadDY (Rockville, US)

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!
