As a Dancing With the Stars pro, Derek Hough knows enough about over-the-top outfits to know a good color can make an outfit pop! That’s why we asked him what he thought of the neon one-shoulder Kaufmanfranco gown his sister Julianne Hough wore to the Rock of Ages premiere on Friday. “I love the choice!” he told InStyle.com. “It’s good. It’s an homage to the ‘80s with that lime electric green.” What a nice brother! Rock of Ages premieres Friday, June 15th.
