Style Gallery: July 23

Audrina Patridge looked Derby-ready at opening day at Del Mar Race Track, donning a dramatic Carol Bader-designed, over-sized black hat to coordinate with her high-waisted black pencil skirt and purple patterned top. Looking hip yet appropriate, The Hills hottie teamed her look with Christian Louboutin pumps, oversize Nicole Richie-worthy shades, and a fierce patent clutch. Talk about one fast-fashioned filly!
