Diane Keaton

Diane Keaton’s Ralph Lauren outfit at the 2004 Oscars was a departure from the glamorous gowns usually seen on the red carpet. The menswear-inspired ensemble consisted of a tuxedo, a bowler hat, and gloves. While the outfit was true to Keaton’s signature style, it was deemed inappropriate for the occasion and considered a red carpet fail.
