Every model who hit the H&M Fall '15 catwalk was smiling ear to ear, making it one of the happiest runways we've ever seen at Fashion Week [1]. Maybe it was the funky '70s fashion that put everyone in a good mood — it's certainly having its effect on us.

Joan Smalls, Gigi Hadid [2], and Kendall Jenner [3] were among the big guns who took to the runway showing off their pearly whites along with a lineup of bell bottoms, jumpsuits, graphic prints, and even a metallic moonsuit — and given that they'll come with the H&M price point, we're grinning, too.
