Demi Lovato, 24, also looked elegant in a lavender gown fit for a princess.
Meanwhile, Olivia Munn, 36, was a vision in red.
MOST NAKED:
Gabrielle Union, 44, was definitely out to turn heads in a barely-there gown that just has to be seen to be believed.
Diane Kruger, 40, also showed a whole lot of leg in a silver minidress.
Mary J. Blige, 46, went the edgy route as well, showing off her toned abs and some underboob in a see-through cut-out dress.
WORST:
As for those who missed the mark, 35-year-old Jessica Alba's ruffle creation definitely wasn't her best.
Mindy Kaling, 37, also had an off night with a loud flower dress.
... And 42-year-old Sarah Paulson's two-tone yellow-and-black gown needs no explanation.
