So You Think You Can Dance host Cat Deeley is giving InStyle the inside scoop about her outfits this season! Read what she says about her looks below, and see all of her Season 8 outfits in the gallery!

“My vintage primrose dress would be perfect for sitting and drinking rose with a handsome suitor and maybe dancing until dawn (I’m thinking of La Colombe D’Or restaurant in Saint Paul de Vence in the South of France particularly!) I wanted the look to be Mediterranean, with a Sophia Loren-inspired black lined eye and messy Penelope Cruz hair. Shoes by Sergio Rossi reflected the feminine theme and Links of London jewelry completed the look.”

Last week, Avon ambassador Reese Witherspoon joined the brand’s Believe World Tour in Moscow and Warsaw, presenting $60,000 grants to the ANNA and Blue Line organizations, respectively. Both organizations are dedicated to preventing violence against women, and the grants were made as part of Avon’s Global Believe Fund, which supports women’s domestic violence shelters and agencies. “I believe we all have a responsibility to raise awareness about the violence that affects one in three women around the world, making it one of the most prevalent, yet underfunded global problems,” Witherspoon told InStyle exclusively. Want to help? Head over to Avon.com and pick up the 2011 Empowerment Bracelet for $10. Proceeds will go toward the Avon Foundation for programs aimed at ending violence against women.
