This is the perfect bikini top, and it only took me 30 years to find. It's sexy, supportive (even for 50 year olds), comfortable, and beautifully cut. I had to exchange for another size and the F&F ladies were super helpful and kindly evaluated awful photos of me in other poorly fitting tops to determine the right size. Shipping was startlingly fast to the US. Will be gradually collecting more colors. Thank you so much ladies!!!

Beware charges if ordering from UK

I really like the bikini, it's a gorgeous deep green and very flattering. I needed to go up a cup size to my usual 30FF but after getting a £60 fee for duties and taxes I didn't want to risk more fees by sending it back for an exchange!

Hey, we're so sorry you got hit by such high duties :( Next time we recommend estimating these fees by using the link at cart so you know what to expect when your parcel arrives!

Legitimately awesome

I’ve struggled for a long time to find swim tops that can actually accommodate my measurements. Finding a band size that is small, but while having enough room is nearly impossible. Not only does this fit- but it is super flattering. I can tell this is going to stay in place on the beach. Also- it doesn’t look like it was made for a grandma- which is what you usually encounter in the size range. The material and hardware feels very chic and high end as well

Reasonable fit

Top fits ok although when worn for an afternoon, I did spill out a little, I don’t feel like the size is wrong just not great if you “wide set” . In saying that it is the best fitting bikini top I have ever worn.

Form and Fold

Hey! The Tri is actually our best style for a wide set bust so it sounds like the size might not be 100% right! You definitely shouldn't be spilling out. If you'd like any fit advice our Fit Specialists would love to help :) You can email us at

Great and flattering, would recommend going up a bra size as a more comfortable fit
