Last night's American Idol got a major boost of style thanks to a super-posh guest judge—Victoria Beckham! She took the judges table by storm wearing two frocks from her own collection—a strong-shouldered red dress and then, our personal favorite, a navy blue sheath with chiffon overlay (left) that put Simon Cowell's staple white v-neck to shame. She even admitted to judging the contestants style as much as their performance: "Even if someone was really not that great, they might have a great pair of shoes on that I really appreciated. I can find something good to say about most people," she told E! after the show.
