We've rounded up 20 of the best celebrity outfits from the past week, including Alexa Chung's pretty Emilia Wickstead dress and Taylor Swift's all-preppy Cynthia Steffe outfit.
Fearne Cotton, 15 August
Fearne Cotton's making the rainy weather work for her in this super cool mac outside the BBC studios in London. Cute mustard shoes too.
Alexa Chung, 14 August
The British fashion icon wears a soft pink Emilia Wickstead dress and sharp Bionda Castana tie-up heels to launch her Nails Inc. collaboration at Debenhams in London on Thursday. Top marks for the mock neck.
Jessica Alba, 14 August
The actress cuts a very Gwen Stefani-esque figure in this awesome get-up at LAX Airport.
Taylor Swift, 14 August
Taylor Swift goes for a triple dose of preppy in this Peter Pan collar Cynthia Steffe dress, Oxford lace-ups and dusky pink Prada tote in New York.
Rosamund Pike, 14 August
Rosamund Pike inducing serious shoe envy outside the BBC studios in London. We assume the monochrome outfit co-ordinating with the pavement is a happy accident.
Kate Mara, 14 August
Black studs and super skinnies. Good one, Kate Mara. She'sat a Television Academy party in Los Angeles.
Sofia Vergara, 14 August
It's mini and floor-length but Sofia Vergara is getting everything right in Andrew Gn at the Hollywood Foreign Press Association Installation Dinner in Los Angeles.
Elle Fanning, 14 August
Elle Fanning dons a Vivienne Westwood corset dress for the dinner.
Olga Kurylenko, 13 August
Olga Kurylenko, your diamantes are dazzling us. She's in Michael van der Ham.
Jenna Coleman, 14 August
Jenna Coleman shows of a gorgeous Dior dress at BBC America's Doctor Who premiere in New York.
Emmy Rossum, 13 August
Clashing prints and mustard stilettos, well done Emmy Rossum - she's out and about in Los Angeles.
Jessie J, 13 August
Cute collarless coat Jessie J. She's mathcing her lips to her tote outside the BBC studios in London.
Rachel Brosnahan, 13 August
We're very keen on Beautiful Creatures star Rachel Brosnahan's monochrome romper, on a shoot in New York.
Jemima Rooper, 12 August
We're big fans of Jemima Rooper and her floaty floral dress at the What If premiere in London.
Ella Eyre, 12 August
Ella Eyre, proving you can't go wrong with a white shirt, also at the What If premiere.
Lizzie Caplan, 12 August
Lizzie Caplan's so cool. The fedora, the navy moccasins, the multiple bags. We want everything.
Jennifer Lopez, 11 August
Jennifer Lopez gets the week off to a fine start in Los Angeles in this '70s inspired navy blue outfit - a loose blouse teamed with L’Agence shorts - and low-key Chanel accessories.
Katie Holmes, 11 August
It's an old Hollywood-style Zac Posen pleated chiffon number with killer cape detail for Katie Holmes at the New York premiere of The Giver.
Odeya Rush, 11 August
Also at The Giver premiere, Odeya Rush makes a big impact in a sweeping scarlet Georges Hobeika gown.
Meryl Streep and Louisa Gummer, 11 August
The best-dressed mother and daughter in Hollywood, probably. They're also at The Giver event.
