Kate Bosworth brought the bizz to the Sundance Film Festival in Utah yesterday, frocking up in a sweet but sexy, Chloè S/S '11 LBD for the Another Happy Day premiere. Kate made her modest crew-necked, knee lengthed frock interesting with a trés sexy cut-out back and leather bodice. Clever girl. Adding some ankle wrap black pumps and semi-sheer tights, Bossy put a little S&M twist on her usually pretty-and-prim red carpet style. Do you like Kate's sexed up ensemble, or do you wish she'd stuck with her usual flirty frock routine?
