On last week's episode of Smash, Ivy Lynn (Megan Hilty) made an entrance at a birthday party for Lyle West (Nick Jonas) in a leopard print Zac Posen dress—and it's not the first time we've seen the look! Celebs like Reese Witherspoon, Kim Kardashian, and Mary J. Blige have also taken the curve-hugging style for a spin. “Zac Posen is one of my personal favorites,” Hilty told “He really knows how to show off the curves of a woman’s body." Shop the dress for $537 at, or try a similar look from Z Spoke, Zac Posen's lower-priced line, for $297 at Then, watch Hilty in a new episode of Smash airing tonight at 10/9c on NBC.
