Christina Aguilera definitely proved that sometimes less is more ... especially when it comes to fashion.

While the singer has been making headlines recently for her very revealing outfits and curvy physique, she hit the stage on "The Voice" last night in her most conservative look in years ... and we're loving it.

With skinny jeans, Christian Louboutin heels, a black top and leather jacket, Aguilera was covered up but still looked cool and sexy as she sang her new duet, "Just a Fool," with costar Blake Shelton.

It's a far cry from the over-the-top ensemble she sported on Sunday night's American Music Awards -- or last week's duet with Cee Le Green, where she wore a tiara, low-cut bustier and thigh-high boots.

Obviously, we've got no problem with Christina's curves (and neither does her cute boyfriend!), we've just been waiting for her to finally wear something a little more form-flattering that also didn't overshadow her voice.
