Even a fashion icon like Barbie can use a little help from Tim Gunn sometimes! For his latest styling venture, the Project Runway mentor dressed two dolls in chic separates like dark denim skinnies, colorful blazers, classic trench coats, and buckled booties, as part of Mattel's Barbie Collector series. Make it work, Barbie! The $30 dolls and $25 accessory packs are set to hit barbiecollector.com and Target stores August 1st.
