Deepika Padukone totally nailed the high slits on the Cannes Red Carpet. She chose to wear a risque custom made jade gown from Brandon Maxwell Fall/Winter 2017 collection. She looked like a diva n the green one shoulder, thigh-high slit gown. 

But do you guys remember that Kareena also rocked the high slit on a Ranbir's dinner party? She was pregnant with Taimur and totally nailed the look. Kareena's olive green one shoulder gown also had a thigh-high slit but of course it was more flowy and had quarter sleeves on one hand.
