Hayley Atwell

Hayley Atwell went for the prom dress look at Marie Claire's Inspire & Mentor launch in association with the Prince's Trust. The actress teamed her shimmering Atelier Mayer dress with egg yolk-yellow clutch bag by Wilbur & Gussie, hair corsage, Jimmy Choo snakeskin heels and violet nails. We love this look –it's all about 50s Mad Men chic brought up-to-date for the teenies.
