Like a dream!

This top is so unique and overall comfy. If you’re like me and you love being in the sun but are not a fan of all the damage that comes with it this is a perfect piece. I love the sweetheart neckline, it is so elegant. The quality of this piece is PERFECTION! I have even used this as a top with super high waisted pants and it is adorable.

The sweetheart neckline is designed to add an elegant touch, and we're delighted to know it resonates with you!

Very good!

Fits like a glove - thank you!

Happy to hear that it fits you well!

Absolute Favorite

I absolutely love this bikini top! It is definitely one of my favorites I own. It’s such a unique style, I don’t own anything else like it. I’m also a complete sucker for thumb holes, I wish everything with long sleeves had them so I love that this top does! The sweetheart neckline is also very flattering. I wish the fabric was not quite as thick because it might be a little more comfortable but definitely won’t be see through

Thank you so much for taking the time to leave such a lovely review! We appreciate your support!

I absolutely ADORE this bikini top, my arms are a bit too short but it still looks amazing, I only purchased the top but now I'm longing for a matching bottom.

Thank you for your lovely review! We're so happy to hear that you love the bikini top - it's perfect for summer days!

Boob spillage

Did not have enough coverage and was a tad too tight in the arms. But loved the design, especially the thumb holes! Could you make it with more coverage and so that it doesn't dig into my breasts and make them look flat? Love your products tho!

Hi there! We're sorry to hear that the coverage was not sufficient and that the fit in the arms was a bit tight. We'll definitely consider your suggestions for more coverage and adjustments to ensure a more comfortable fit around the bust area in future designs.

definitely don't buy if above b or c cup

Squishes any boobs down flat into hideous quadriboob. Definitely in part because of the wire, so the boobs have nowhere to go but over. If the cup were completely soft, then they could be stretched, but with that over-wire they're just like... cut in half. Not great

We genuinely appreciate your honesty, and we understand the importance of providing products that cater to various body types and sizes. Your feedback about the wire and its impact on the fit is crucial, and we'll certainly consider this as we work on improving our designs. Thanks for your review.
