The sleek bodysuit is a terrific foundation for just about any outfit, whether you’re going for a casual look or something dressier. No longer simply a leotard, the figure-flattering bodysuit can be a structured button down, a flowy blouse, a textured sweater, or a sexy evening piece. Bodysuits are a favorite for layering since you never have to worry about tucking them back in.
