So cute, so innocent.

We hope it lasts!

Kendall and Kylie Jenner strutted down the runway at The Heart Truth’s Red Dress Collection presentation during New York Fashion Week on Wednesday.

The girls looked beautiful in bold red Badgley Mischka gowns with their long dark hair trailing down their backs.

Kendall was definitely the more risque of the two in a beaded cap-sleeve gown with a keyhole cut-out at the bust, while Kylie looked demure in her sleeveless dress. That is, until she turned around to reveal a draped open back!

Nice!
