Stays on my 36DDDs!

I'm super impressed with this top.

So happy to know it met your expectations! Thank you for your review!

Not for big boobs

I think Cassie did a great job for this being her first swim launch, but I definitely would not recommend this for people with larger boobs and a small waist. There just wasn’t enough support and it fell down with the straps on. Also the pads, although non removable, are not sewn in so they get moved around a lot. I definitely think this is a great swimsuit for smaller people, though!

Thank you for your review

Snug but fits and it's def staying on!

Fabric is high quality and it's a snug fit but snug enough for me to fit and not have to worry about it moving around if I were to jump in the pool. I'm 5'3, 135 lbs, 36D so I usually order size Large for sports bras and workout tanks with built in bras. Although it's snug I can adjust the strings in the back and love that it came with shoulder straps too. Also I'm 28/29 on bottoms so I order size Medium for the matching bikini bottom.

Great review! Thanks for writing it!

I needed a bigger size, sold out

It was a little too snug on my chest. I’d go for a size up but it was sold out. Such great quality and so cute, not surprised it sold out!

We appreciate you sharing your review!


I’m impressed to say the least. I typically give Cassey’s new items a couple drops before diving in to the purchase. I’ve found that sometimes it takes a couple tries to find the best fit for everyone, especially curvier girls (in general, not just Popflex!). The reason I come back is because Cassey LISTENS!! She uses the reviews and makes something even better than before…


I have no words. It’s perfect. I’m so glad Cassey waited a while and tried as many variants as possible. This is now my go-to swim top because it actually does what it’s made to do — stay in place! Not once have I used the straps. And the corset back… pure genius. It’s feminine, it allows for size adjustments. I can fluctuate in weight and know that this top isn’t going anywhere.

Thank you Cassey for creating every woman’s dream swim top!

Thank you for leaving us a review and we really appreciate you taking the time to share your experience and rating with us. Best!

I’m about 5’0 34D and 33 in around my hips. Let me tell you the medium top and XS bottom fit perfect.

Thank you for your review! We are glad to hear you found the perfect fit!
