size 14 little black dress, sheath style

This little black dress is made for a curvy woman who wears size 14 or so. It's in excellent used condition. One comment: I bought it without a 2nd piece (jacket?), but the tag says it was originally a two-piece set. It was made in the USA, and is made of a rayon/acetate blend. Approx measurements: pit to pit 19", shoulder to bottom hem 38".
