On Monday, Emma Watson attended the premiere of her latest flick "The Perks of Being a Wallflower" … and she definitely didn't go unnoticed.
The 22-year-old looked stunning in a nude rhinestone embellished backless gown, except the dress looked like it was one size too big on the "Harry Potter" starlet -- exposing her left nipple pasty!
While embarrassing, we credit Emma for at least having the good sense to wear them in the first place.
Wardrobe malfunction aside, Watson looked elegant and timeless in the lace ensemble, especially with slicked back hair and bold red lips.
Other stars who hit the red carpet for the premiere were Rumer Willis, who missed the mark in her black halter getup, "The Vampire Diaries" star Nina Dobrev, who looked radiant in a red lace dress, and Kate Walsh, who stunned as usual in a black heart-shaped mini.
