Going to be a summer camp counselor this year, looking for a new swimsuit to fit the gig.

This summer I'm going to be working as a counselor at a Jewish summer camp located in the United States. Honestly, I have no idea what's appropriate as far as swimwear goes, but I can almost guarantee that the only piece of swimwear I currently own is not appropriate. I own something very similar to this, purchased a few years back.

I'm sure I can ask some of my fellow employee's what some big no-no's are, but as I won't be seeing them until mid-June I figured I could take some advice from ya'll. If more information is necessary, I'd be happy to provide it.

I'm basically just looking for suggestions as to what I should gear my searches toward, not for any swimsuit in specific (unless you know of something absolutely amazing that I need to check out). I'm gearing more towards a one piece, but would feel uncomfortable in something like the Olympics swim teams wear.
