Customer Reviews

Overall rating: 4.9 / 5 from 29 reviews.

Ordered the matching set for the 003 and the bottom it is very little as described. I will be using for tanning so no complaining. The color is just gorgeous. It's a very beautiful bright yellow. If I buy this model again I will try the medium instead for the bottom to see if provides a little more coverage for me. Anyway I like it and I do recommend.

This bikini is super sexy and also somehing I feel like I can live in. I didn’t have to worry about it falling out of place. It’s is a large top and a medium bottom. I am 130 lbs and 5’4” with a muscular build and 34DDD. I can’t wait to buy more!

Nicole P. 5/5 Verified

I absolutely love this bikini! The blue color is so pretty and vibrant, especially in the sun. It was comfortable to wear all day, even while paddle boarding and swimming, and stayed in place really well. Such a cute bikini for summer and definitely one of my favorites!

This swim suit is great quality and super cute fit! i love!

Kiera I. 5/5 Verified

i love how tiny it is bc i feel like most bikini bottoms sit kinda weird on my butt and easily become uneven or will look diapery. not these!! my one gripe is that i feel like the sides of the front of the bikini do not adhere that tightly to my body. it’s not too big of a deal but i do wish it fit better right there. i think i might size down to an XS next time, but the size chart told me i would be a S.

This piece is very well made with bright colors. I did return it because i didn’t love the style on me. I exchanged for a different bottom that will be more flattering. Nothing wrong with this piece if is your style preference.
