Dear Olivia Wilde, what is your secret to living life in the fab lane just six weeks after giving birth? The 30-year-old actress gave birth to her first son, Otis Alexander, this past April with fiancé Jason Sudeikis, and not only did she hit the red carpet 12 days after delivering, she’s back for the 2014 CFDA Awards six weeks later. How does she do it?

The starlet showed off her post-baby body in a svelte vintage Mollie Parnis number courtesy of Decades. What’s even more interesting is the same dress in question was also worn by Anjelica Huston during the 1974 Cannes Film Festival. Talk about a dress legacy!

It seems as if Anjelica’s dress gave Olivia some extra pizazz at the awards because girlfriend was stunning. Not to mention the fact that this new momma still has her after-baby glow. #BowDown.

Speaking of babies, we have yet to formally meet little Otis, but Olivia has been sure to keep her fans updated on her various experiences with motherhood thanks to her witty remarks on Twitter. For starters, the new mother learned an awful lot about boys during her first days as a mom.

“Having an infant son alerts me to the fact that every man, at one point, has peed on his own face. #awesome,” Olivia tweeted just one day after announcing the birth of her son.

Olivia also shared the issues she runs into as a mother who breastfeeds. “This year, instead of attending the ‘Met Gala’, I leaked milk, and ate an entire napkin while inhaling a felafel.” Oh Olivia, we love you!

How great does Olivia look these days? Tell us your thoughts in the comments below!
