Wore it for the first time today. The ‘girls’ felt well supported and the top was very comfortable. I’ve had difficulty finding something both supportive and suitable for pools for water aerobics since my favourite small business retired. (I’ve tried some other brands, paid a fortune, only to be disappointed when foam and linings disintegrated in our salt pool within a few weeks) Love the pattern – my daughter eyed it off with a gleam in her eye… I will be keeping an eye out for more patterns.
