Perhaps inspired by the recent release of the "Star Trek" movie, pop stars at last night's "MTV Movie Awards" dressed like they had just stepped off the USS Enterprise.

Being that the cable network giant caters to such a young crowd, it was no surprise that micro-mini dresses were the biggest trend of the night. Youngsters like Ashley Tisdale (in an Elise Øverland dress and Paul & Joe Sister heels), Kristen Stewart, Megan Fox, and Leighton Meester all came baring their thighs, as did industry fashion favorites Sienna Miller and Sandra Bullock.

Check out our "MTV Movie Awards" gallery below and vote on who you think rocked the fashion-forward trend and who was just a style space case.
