Would be great with different cup size options

Wrong sizing for me. The band was too loose for the cup size. If I had sized down, the cup would be too small. Lovely bikini top though - great quality and I loved the gold metal detailing.

My best bikini ever, love the style, love the fabric and the fit is perfect. No issues with pool or sea water affecting the fabric or fasteners.

Great quality fabric and very good fit. I ordered a medium, but had to send it back for a small.

Really flattering with the padded cups. The top has stayed in place whilst I’ve swum and surfed

Excellent quality item

Excellent quality item, thick material and solid fastenings. It gets four stars, not because there's anything wrong with it, but because I bought the wrong size and so it doesn't fit. I know I shouldn't take a star for my own bad decisions, but such is life. I prefer my swimwear not to be super tight and squeezey, so I have a tendency to size up. It worked for the blikin bottoms, but not much for the top.

Lovely flattering bottom top too small
Originally posted on sweatybetty.com
No, I don't recommend this
Beautiful flattering bottoms but once again disappointing top with ups too small for my 36E cup size. Reluctantly had to return both L and XL.
