Photocall: Sienna Miller

Whoever started the rumor that Sienna Miller is a style icon needs to be taken out back and beaten senseless with a copy of Vogue. We've seen Miller appear in the tabs time and time again looking like she's been getting fashion tips from Mary Kate Olsen. Now this photo, courtesy of TMZ, shows Miller and her mom in matching outfits that almost defy description. Pity James Franco for being the meat in this cowboy luau sandwich.
