Best swimsuits for the average sized woman?? Where??

[multitasker]

All the high street stores seem to be full of bikinis which is all very lovely but I would love a decent one piece that isn't all black and looking like a serious speedo one. Any suggestions? Online stores?

bhs has a good range usually?

I was in Sainsburys a couple of weeks ago and should've had a closer look - will have to look harder...
