Designers aren't the only people to debut new looks during New York Fashion Week!

Case in point: Taylor Momsen looked pretty unrecognizable at Alice + Olivia's runway show on Monday.

Gone were her trademark kohl-rimmed eyes in favor of eye makeup that looked—gasp!—Gossip Girl glam!

Instead, the 20-year-old went for a look that was just as fresh as the spring fashions designers sent down the runway.

Momsen brought out her baby blues with neutral shadows, which she complemented with a glossy red lip. While subtle earth-tone hues tend to be reserved for the daytime, Momsen proved they can pack quite the dramatic punch when layered for a sexy smokey eye effect.
