One glance at Sharon Stone and you forget she's 53!

The Basic Instinct actress headed to the Tavern in Brentwood looking absolutely fabulous in a black dress, sexy stockings and wickedly wild stilettos. Guess she was so busy getting her chic ensemble ready, she forgot her bra. Talk about a killer instinct for fashion!

Ms. Stone seems to be in the best of moods following lunch with friends. Why wouldn't she be smiling? If we were rockin' that kind of bod at her age, we'd be grinning non-stop, too.
