Hilary Duff picked a Marchesa Spring '11-esque top knot and a glossy berry lip to sign copies of her new book, Elixir, in Paris yesterday. She teamed it with dark, defined brows and a pop of pink of the cheeks. I like the chillaxed vibe that the double-bun hairstyle gives to the look. You too? Or do you like it when Hilary wears her hair out?
