This is a 1950's Ben Zuckerman suit in grey wool. It's a feminine delight! The skirt is gently flared and falls to below the knee.
The real standout is the jacket- it nips at the waist and is trimmed in a paler grey grosgrain ribbon with ribbon rosettes as buttons.
The suit was sold at the French Shops at Filene's, Boston. This venerable store was opened in 1881. The French shop started out selling only French models, but by 1940 it also carried the cream of American designers. Filene's closed in 2006.
