We have Bella Hadid to thank for the hottest trend on the red carpets right now.

She took the traditional slit skirt up a few notches at the 2016 Cannes Film Festival wearing a slinky Alexandre Vauthier design in fiery red. Since then she’s made headlines for other dresses featuring the high side slit, most recently an exquisite sheer Ralph & Russo Couture creation covered in crystals. Many other celebs have given the sky high slit a try. Some, like Mariah Carey, play up the sexy side of the trend, while others, such as Emma Watson, reveal just a peek of skin in more modest ensembles. — jas
