Dipped in the Dead Sea wearing it
Originally posted on sweatybetty.com
The quality is excellent. I tested it by dipping in the Dead Sea; it kept its shape. I wear it for laps as well. Moreover, it’s very stylish and elegant.

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.

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.
