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."
