Ashlee Simpson Wearing Red Leather Shorts

Ashlee Simpson attended a party for the Samsung Galaxy S III last night in NYC, and for the occasion she mixed leather with silk. Up top she wore a white silk button-down Alice + Olivia blouse ($275) and on bottom a pair of Alice + Olivia red leather shorts ($198, originally $396), which clearly stole the show. We also love how she did the trendy half tuck with her top. Ashlee's go-to Jennifer Zeuner arrow necklace ($149), a bevy of rings, black booties, and a black clutch completed her cool-slash-chic ensemble.
