Please help - suggestions for a flattering swimsuit

[hippmummy]

Unfortunately my bikini days are over, thanks to stretch marks and mummy pot belly.
I really need a nice all in one swimsuit for the summer.
Any suggestions where to shop? I don't really go shopping very often anymore (bloody kids - mess up your body then won't let you buy new clothes ) so don't know where to start or what's around. I will be in London over the next few weeks so I can make the most of the choice of shops. Also happy to shop online.
I am size 10, but need something with bust support, and maybe some tummy control as I wont get round to doing those 50 sit-ups a day!
Any help gratefully received x

Try figleaves.com and swimhut.com, both have good ranges and some pretty swimsuits. Have found some decent things in M&S in the past too. Hope you find sth you like...

Debenhams have them with the reinforced tum.

Thanks for the suggestions ladies!
Quite surprised at how nice some of the stuff is . I always got the impression that shops made a real effort with bikinis but swimsuits were a bit frumpier. Glad to see things have changed!

i have been wondering wht the Boden swimsuits are liek to wear....anyone have one?
