Red Carpet Wrap: Sienna Miller, Michelle Rodriguez, Alicia Vikander, Marion Cotillard

Sienna Miller chose this stunning Gucci gown for the Cannes Film Festival.

The colour is beautiful but the rose-gold belt, leather bodice, and pleated lace skirt make this dress really special.

The tousled, half-plaited hairdo is true to her signature underdone style.

Michelle Rodriguez managed to find a gown that is both dull and a flash risk for the same premiere.

This high-necked Vionnet gown looks semi-sheer in some shots.

The design is from next season’s collection but this particular choice doesn’t suit such a summery event.

Alicia Vikander flattered her Cannes tan with this silver-grey Valentino Couture gown at the Macbeth premiere.

The cloak-train hybrid at her back makes the otherwise classic design look very modern.

She accessorised with Boucheron jewellery and a simple bun.

Marion Cotillard went with a jewel of a Christian Dior Haute Couture dress for the Cannes Film Festival premiere of Macbeth.

The heavy embellishment made this mini special enough for formal evening wear.

She accessorised with Chopard diamonds and wet-look hair.
