We know it’s Mercedes-Benz Fashion Week, but when did it become okay to rock a bathing suit out on the town?

Reality star Kristin Cavallari started off the night in an orange dress designed by Jessica Barkley, but soon stripped down to a revealing blue one-piece at the Diesel show in Miami.

Nude heels and fancy fringe didn’t stop her outfit from looking any less like beachwear.

But we guess when you have a body like that, it doesn’t really matter.
