Plain but flattering swimming costume?

[permaquandry]

I don't own a swimming costume and don't want to wear a bikini when taking kids swimming.

Can anybody recommend a place to buy or even and actual costume that is a) flattering b) trendy and c) not expensive.

I am a size 8 and an okish figure, with fairly 'empty' boobs, so need a bit of support and uplift!

Debenhams have a great range (and I've insider knowledge that they are designing for the summer a proper push up swimsuit!)

Marks also have some swimsuits with padding

Sweaty Betty or Landsend sales both good
