As a member of this year's Cannes Film Festival jury, Kristen Stewart has been making plenty of stylish appearances since it all kicked off on the French Riviera last Monday, but this weekend, the actress outdid herself. From a girly strapless gown to the most summer-perfect Chanel trouser suit, we break down Stewart's impeccably stylish weekend.

1. The summer trouser suit

For the premiere of Girls of the Sun on Saturday night – where Stewart took part in a protest about the lack of female film makers – the actress stuck to her faultless fashion formula of Chanel plus trouser suit.

Stewart wore a trademark Chanel white trouser suit with black piping and gold buttons, which she wore partly unbuttoned with a nude camisole underneath. The actress paired the ensemble with tiny statement sunglasses, black heeled boots, a bold red lip and slicked back 'do.

2. The ladylike gown

Although Stewart often sticks to her trademark androgynous look, she proved once again how versatile her style can be when she attended the Women in Motion Awards Dinner on Sunday evening by showing up in a strapless, embellished gown with dainty white heels.

3. The dressed-down summer look

Her third look of the weekend came in the form of a much more casual ensemble, but equally as stylish. As she made her way around the festival (presumably between screenings), Stewart teamed a pair of light-wash denim jeans with a chic black blazer, a slinky white top and a pair of patent brogues.
