One Piece

My boyfriend's mother is very conservative, so I was thinking about buying a one-piece bathing suit for those times when I need to look more demure. Well, nevermind because apparently every moderately-priced one piece is either the ugliest old lady pattern ever, a boring black suit to make you look skinny or ribbon sewn together for a stripper-tastic look. Where are the cute, trendy one pieces in fun prints and shapes? I was surprised to find a few on Newport News (swim dresses are kinda fun!), but it seems you have to spend a lot of money on a cute one-piece suit. Any suggestions?
Here's a swimdress for $34:
