When Jennifer Lawrence shimmied out of her red Dior gown after the Oscars and changed into a mirrored Tom Ford dress for the Vanity Fair after party, she didn't bother putting underwear back on!

The sheer, thigh-length dress — from Tom Ford's Spring 2014 collection — made it obvious that the 23-year-old actress wasn't wearing anything beneath. (Nor should she for a dress like that and with a body like hers!)

If the shimmery dress looks familiar, it might be because Kate Hudson also wore the dazzling creation in the pages of Harper's Bazaar.

Jen also rocked Tom Ford pumps and a Neil Lane diamond ring for the occasion.

Even though she lost the Best Supporting Actress race to 12 Years a Slave's Lupita Nyong'o — Jen was up for the award for her performance in American Hustle, her third Oscar nomination — she still had a busy night.

She fell on the red carpet, shaked her arm fat, cuddled next to boyfriend Nicholas Hoult, endured playful teasing by host Ellen DeGeneres, freaked out over Kevin Spacey's House of Cards moment, and presented the Best Actor trophy to Matthew McConaughey.

She may be an Oscar loser this year, but she'll always be a winner in our book — especially with looks like these!
