Have to go shopping now! Behati Prinsloo stepped out in a sexy Pretty Woman costume for Halloween Monday, October 31, one month after giving birth to her daughter, Dusty Rose. 

The first-time mom, 27, wore a short blonde wig, hoop earrings, thigh-high black latex boots and a replica of the cutout dress Julia Roberts wore to play Vivian, the hooker with a heart of gold, in the 1990s rom-com.

Prinsloo was accompanied by her husband, Adam Levine, who dressed as Led Zeppelin frontman Robert Plant.

The Victoria’s Secret model and Maroon 5 singer welcomed their first child September 21. They shared the first photo of their little girl two days later, on September 23. 

"Words can't describe 💗 Dusty Rose Levine 9/21/16,” Prinsloo captioned an Instagram photo of Dusty nestled against Levine’s bare chest.

Prinsloo was ready to return to her social life. The stunner documented her first postbaby girls’ night out on Instagram October 16. “After 3 weeks of breastfeeding every 3 hours, no sleep and nursing my nipples back to life lol, I left the house to see my girls for dinner. Life is so beautiful, can't believe how lucky i got 👨‍👩‍👧,” she captioned a mirror selfie before leaving the house.
