Today's is a special-edition Lipstick Diary. As soon as I spotted a sassy young diva in this delicious shade, I knew we'd have to face off on who wore it better. The lipstick is YSL Rouge Volupté in #10 Provocative Pink, $38. And the little star rocking an innovative, artistic self-application is Isla Crossingham, almost three years old and daughter to Lesa Hannah, beauty editor at FASHION Magazine.

So. Who wore it better?
