TV Fashion: 'The Voice,' 'Vampire Diaries,' 'Mad Men' & More Best And Worst Dressed For The Week Of May 4-10 (PHOTOS)

It was the finale of "The Voice" this week, so we wouldn't dare deny Christina Aguilera one last appearance as the reigning queen of "where are your pants?" on our TV's worst dressed list.

But she wasn't alone in her style misstep -- this week saw flashback faux pas from some of TV's hottest characters, including our beloved Elena (Nina Dobrev), who rocked an unfortunately ill-fitting cheerleading uniform for the big "Vampire Diaries" season finale, and hot, brooding Jack Porter (Nick Wechsler), who was hiding under a stringy black Raggedy Ann wig in "Revenge" flashbacks.

Thankfully, there were some all-time best dressed looks to get us through, like a sexy duet for Ivy (Megan Hilty) and Karen (Katharine McPhee) on "Smash" that finally showed off their assets ("Real Housewives of Atlanta" star Phaedra would not hesitate to call these what they are: donkey booties), and an entire episode full of shining style moments for Megan Draper (Jessica Pare) on "Mad Men." Seriously ... can we live in her closet?
