What kind of swimsuit do you wear

What kind of swimsuit do you wear? I've worn the same white J.Crew two-piece mostly out of habit for my entire adult life, but it just sold out. After 10 years! And when I called customer service, they said they didn't know if they'd ever get it back in stock. So, now I'm officially on the hunt for a new suit. I'd actually like to try a one-piece for running around with the boys this year. They're so elegant and flattering, don't you think?

Where do you shop for swimsuits? Any suggestions?
