Christina Aguilera's return to The Voice in its fifth season has been nothing short of spectacular. The singer, now in her fourth season on the NBC reality show (she took time off during the show's last season), has picked a team of worthy contestants (Matthew Schuler and Jacquie Lee) and is really coming into her own as a coach and mentor. She has performed in some of the season's most memorable musical numbers (including this performance of "Say Something" with A Great Big World), and her banter with fellow coaches Blake Shelton, CeeLo Green, and Adam Levine is more fun than ever. By all estimations, Aguilera is at the top of her game - and this includes her fashion game.

Aguilera, who recently slimmed down, has wowed with her fashion choices so far. Whether it's a sexy L.B.D. or demure camel-hued sweater, the formerly "Dirrty" singer has proven less is more - except for the occasional pants-less performance outfit. Hey, we did say "most of the time."

Take a look at Aguilera's most fashionable looks of the season.
