I've just returned from Center Parcs where i spent a lot of time noticing ladies' swimming costumes..... and being ashamed of my own greyish black one that has really needed replaced for some time!
I spotted one in particular that i loved and wished i had asked the lady where it was from. It was a black halterneck one piece with a red and white spotty band under the bust which clipped at the back. It got me a thinking - where do you buy swimsuits that help give you good shape - I usually buy in Next but would like to go a step up in the hope of getting something a bit more flattering for me not skinny figure!
Land's End to quite nice, figure "helping" swim suits all year round. John Lewis have them in all year too, from flimsy to girder and all sorts in between. Probably best to avoid fashion brands like Next if you want figure enhancing.
