BEST: Ruth Negga
Irish-Ethiopian actress Ruth Negga may not have taken home an award for Best Actress, but she won the red carpet at the Vanity Fair Oscars After Party in this stunning Oscar De La Renta gown.
BEST: Kate Bosworth
Kate Bosworth is a vision of beauty in this stunning gown.
BEST: Mindy Kaling
Comedian and actor Mindy Kaling made both florals and bold colours work for the red carpet in this stand-out dress.
WORST: Diane Kruger
Had this dress been full length, it would have looked incredible. However, the shorter length and train at the front do not equate to a show-stopping piece for Diane Kruger.
BEST: Rooney Mara
Rooney Mara proves that sometimes less is more in this simple but beautiful dress.
WORST: Reese Witherspoon
There's nothing particularly wrong with this dress, but we feel that it's a safe and borderline boring option for the Oscar-winning actress.
BEST: Jessica Alba
This might just be Jessica Alba's best look yet.
BEST: Jennifer Aniston
Jennifer Aniston looks more and more incredible as the years go on.
BEST: Amy Adams
A shimmering, sparkling gown is a fail-safe option for the biggest event in the celebrity calendar.
WORST: Gabrielle Union
Half bikini, half dress, we don't know what Gabrielle Union was thinking with this one.
BEST: Olivia Munn
Olivia Munn knows how to work the red carpet, that's for sure.
BEST/WORST: Mary J Blige
Best, for her incredible, figure-hugging dress. Worst, for the Coconut Head hair.
BEST: Emily Ratajkowski
The 25-year-old model can do no wrong.
BEST: Kate Upton
The Sports Illustrated cover star is the definition of Hollywood glamour, from her dress to her hair.
WORST: Dakota Johnson
We're not sold on the Fifty Shades actress' statement bow that looks like it was put on at the last minute.
Ciara is positively breath-taking in this red velvet dress.
BEST: Kate Huson
The Almost Famous actress nails red carpet style on the head.
WORST: Sarah Paulson
Mustard suits the American Horror Story star, but the ruched sleeve on one side and black sleeve on the other make for a confusing piece.
BEST: Rosie Huntington-Whiteley
The mother-to-be is our best dressed star of the night.
BEST: Freida Pinto
Slumdog Millionaire actress Freida Pinto stood out from the crowd in this aqua colour dress.
BEST: Katy Perry
Katy's Jean Paul Gaultier piece isn't show-stopping by any means, but she still looks incredible.
BEST: Sofia Vergara
Sofia Vergara must have dozens of these dresses in her wardrobe as they're all we ever see her in, but, as they say, if it ain't broke, don't fix it.
WORST: Demi Lovato
Lilac looks amazing on the Disney star, but a dress shaped like a toilet roll cosy does not.
BEST: Allison Williams
The Girls actress' movie star look is a winner.
BEST: Elizabeth Banks
Elizabeth Banks looks like an ethereal goddess.
BEST: Molly Sims
Another safe option, but Molly Sims is a bombshell in this glamorous gown.
BEST: Lily Collins
Lily Collins is fast cementing herself as one of the best dressed celebrities on every red carpet.
BEST: Kate Beckinsale
With so much going on, this dress shouldn't work, but somehow it does.
WORST: Nina Agdal
Leonardo Di Caprio's other half loses her best dressed title for the nineties style belt that looks totally out of place.
BEST: Thandi Newton
There's not one thing we don't love about Thandi's Schiaparelli Couture gown.
