Game Over: Kate Moss Had The Best Leg Slit at Cannes

The red-carpet snaps from the Cannes Film Festival are pouring in so fast, we can hardly keep track of all the glamour. And then, there was the shut-it-down moment that made us all pause. (Well, after the Julia-toe-ring moment.) After 15 years of absence from the festival, Kate Moss made a dramatic appearance on Monday. Like your '90s icons in red? Then you'll love this: 

The asymmetrical, one-shoulder dress was custom made by Halston Heritage. Let's all note the split-thigh construction, Chopard bling, and towering peep-toe heels. Oh, did you miss the leg slit? Allow Kate to demonstrate: 

Here we have it from the side.

Aha, there it is full on. Yep, she's giving us some major leg.

Kate's date was none other than her gorgeous half-sister Lottie Moss, who also demonstrated how red dresses are done. Lottie, making her Cannes debut, wore a backless gown from Dior with a matching red mani, and a sparkling statement necklace.
