Clothing by Renié
Renié’s flattering cocktail dress is in black satin with a chiffon insert over the chest, topped with a choker-like jeweled collar. Marilyn wore this dress in a scene from As Young As You Feel, with a heavily sequined black chiffon wrap. Directly from the set Marilyn wore this dress, sans the wrap and with a change of gloves (in the film they are white), to a party on the Fox lot for a group of visiting exhibitors and columnists.
