First of all, take another close look at all the possible suits.
Pay particularly close attention to the colors and to any prints.
You may like the color and design, but you have to be honest with yourself.
Is it flattering? Would you actually be comfortable, being seen in public wearing that style?
Remember, just because a bathing suit is the epitome of sexy on the hanger and even in the fitting room, it might be a bit too much when you are out in public.
