Olivia Culpo is jaw-dropping in silver cut-out dress

Olivia Culpo turned heads last night at New York Fashion Week's Kick-Off Party hosted by E!, ELLE & IMG.

The 26-year-old model stepped out wearing an embellished halter-neck dress by Julien Macdonald. The gun-metal-toned dress featured side cut-outs and a front slit - showing off her sexy 5'7" figure. Culpo finished off her look with silver pointed-toe pumps and high-pony that accentuated her stunning cheekbones.

Earlier in the evening, the former Miss Universe attended the #FeedYourBeauty Vital Proteins launch alongside Shea Marie, where she rocked a head-to-toe Fendi ensemble, making headlines for her twinning fashion moment with Priyanka Chopra.

Other A-listers in attendance at the E! ELLE Kick-Off party included Nicki Minaj, Francia Raisa, Melissa Gorga, and Ashlee Simpson. Check out the gallery above for photos of the star-studded event.
