Wait, What?! Taylor Momsen Gives Up Grunge, Looks Ladylike in Lace at Marchesa Show

Pretty Reckless singer says the designs are "ladylike" and "make you feel like a woman;" Jenna Dewan, Petra Nemcova, Stacy Keibler and Bar Rafeali also attend the show

Is that really you, Taylor Momsen?

The Pretty Reckless frontwoman ditched her signature grunge look for glam Wednesday at the Marchesa show during New York Fashion Week.

Stunning in a sheer, lacy dress by the brand, the 18-year-old singer toned the eyeliner down a notch and wore her hair in an elegant updo.

So what did the former Gossip Girl star think of her first "official" show?

"It was f--king—excuse me...It was beautiful. It was gorgeous," she told E! News.

"There were so many [designs] I loved," she gushed.

As for why she likes the brand? "[It's] ladylike," she said of Georgina Chapman and Kerin Craig's creations. "[They make] you feel like a woman. Everything [they do] is beautiful and it crosses so many different styles. I think any woman can wear Marchesa and look beautiful in it."

Other women who apparently share Taylor's love for Marchesa include Jenna Dewan, Petra Nemcova, Stacy Keibler and Bar Refaeli, who all sat front row at the show.
