i brought a nice one a few years back from Simply Be it was a tankini with a skirt with built in knickers (they still do on with a skirt now) and its so flattering on your thighs and it covers the tops of your legs which for me personally is a real bonus. I also managed to get a tankini top this year from Evans with underwire which for someone with huge boobs was excellent and gave me a bit of uplift lol.
Hope you find something.
