Red-headed Rumer Willis rocks out a nautical-print D&G halter cocktail dress at the D&G flagship boutique opening on Robertson Boulevard, Beverly Hills on Monday.

Last month, Bruce Willis said of 20-year-old daughter, “I worry about her being in showbiz. It is full of people like me. She has turned out so well. We did not push her into acting. She just sat me and Demi [Moore] down and said: ‘Look, I know you both think you’re big shots but I don’t want any help. I want to do this by myself.’”
