Maybe a pink one, not to light pink but not to bright pink. I would also try a pattern with many colors including light and dark colors but not only one of them. The pattern would not only take away attention from your fair skin tone but, also the many colors will make you look tanner. Stay away from any white though, that would wash you out. I would suggest a bathing suit some what like this: http://www.victoriassecret.com/ss/Satellite?ProductID=1265499099956&c=Page&cid=1265504495899&pagename=vsdWrapper
