Karlie Kloss may be famous as a lingerie model but the 21-year-old beauty went braless at the 2013 Victoria's Secret Fashion Show afterparty held on Wednesday, November 13th at TAO Downtown in New York City.

According to E! News, following her walk down the runway the model posed in a sexy white dress that featured a plunging neckline and a strategically located geometric cut-out which exposed an ample amount of underboob.

Kloss glared at the cameras as she struck a sultry pose on the pink carpet. Earlier in the evening the model wore an array of sexy bras and panties as she made her way down the catwalk set up at the 69th Regiment Armory.

She also rocked the memorable glitter and sheer Snow Angel bodysuit for the show and took to her Instagram account to post a sexy shot of herself in it from behind.

In the caption she wrote, "What do you think of my #SnowAngel bodysuit for the @victoriassecret #VSFashionShow?"

Karlie Kloss also seemed pretty excited to share the runway with country cutie Taylor Swift.

She posted a photo of the two to her account that featured confetti falling around them, as they danced towards on another during the show.

The model captioned the photo, "I knew you were trouble... @TaylorSwift rocking it on the @VictoriasSecret #VSFashionShow Runway!"
