Best Dressed of the Week: Helen Mirren, Cate Blanchett and Winnie Harlow take the lead

It's been a whirlwind week for style, with many of the most acclaimed stars and models in Hollywood taking the red carpet for the annual Cannes Film Festival.

Amongst our favorites of the week include Winnie Harlow's dramatic metallic gown by Jean-Louis Sabaji, Iskra Lawrence's princess-esque dress by Terani Couture, Cate Blanchett's pure white silhouette by Armani and Helen Mirren's chic street style in Boden.

One standout look we can't get over? British actress Emilia Clarke, who took on the annual festival in the south of France to promote her new film Solo: A Star Wars Story. The actress, who also stars in Game of Thrones, stunned in a breathtaking purple tulle gown by Dior. It was a bold choice for the star, especially given the color and asymmetrical cut.

Other sartorial favorites this week include Ginnifer Goodwin, Blake Lively, Alison Brie and Mandy Moore. Scroll through above to see our favorite looks!
