Rumer Willis just showed a little more than she'd probably like to!
The daughter of Demi Moore and Bruce Willis hit the red carpet on Tuesday for Elle's 5th Annual Women in Music event in Hollywood, California.
Sporting a black, cut-out mini dress, Willis showed off her amazing figure ... and her pink panties at the celebration.
The giant cut-outs in the side of her dress revealed too much skin when she posed from the side -- at least she was wearing underwear!
The 25-year-old normally looks great on the red carpet ... so, we'll let this fashion faux pas slide this time.
