This is a beautiful set for Spring. It is in excellent used condition.The bustier has a gold zipper, boning and is lined. Its a cotton spandex blend. The light cover up is a knited mesh duster. The size on the bustier says 10, but truly an 8. The size on the duster says large but it's definitely more of a medium. It is a nylon rayon blend. Thanks for looking. Bustier length 15.5" waist 32" bust 37" Duster sleeves 32" length 41"
