Both reviled and adored by fashion critics, Molly Ringwald's dress in Pretty in Pink (1986) defined the 1980s prom dress. Created by combining a thrift store purchase with a hand-me-hand gown, the handmade dress helped Ringwald's character Andie capture the eye of former beau Blane. (His name is Blane? Oh! That's a major appliance. That's not a name.)
