BEST: Ellie Goulding
Ellie Goulding was the first to arrive on the red carpet and she set the bar sky high for the rest of the night as she smouldered in this jewelled, black gown.
BEST: Katy Perry
We wouldn't expect anything less than amazing with Roar songstress Katy Perry.
WORST: Eliza Cummings
Put simply, this dress is what nightmares are made of.
BEST: Abbey Clancy
This monochrome, asymmetrical dress is a safe bet for Abbey Clancy, but we can't help but love it.
WORST: Fearne Cotton
While there's nothing wrong with Fearne's LBD, we miss her bright and bold style and feel this really lets her down.
WORST: Charlotte Crosby
We have one question and one question only: What was she thinking?!
BEST: Mollie King
Only Mollie King could make this shimmering mini dress and oversized fur stole combination look so good.
We love the matching crop top and skirt, but the print on it is hurting our eyes.
BEST: Rita Ora
The sheer material of the bottom half of this dress does Rita Ora no favours, but her badass hair and makeup and the embellished top half make it work.
BEST: Lianne La Havas
Now this is how you wear a sheer, embroidered, shimmery dress. Kudos to Lianne La Havas for pulling this off.
BEST: Michelle Keegan
This could be a photo of Michelle Keegan from seven years ago and we wouldn't be able to tell. As they say, if it ain't broke don't fix it.
WORST: Pixie Lott
Gladiator chic should never be inspiration for an outfit.
BEST: Emma Willis
Co-host Emma Willis looked simply stunning in this classic black gown.
WORST: Charlie XCX
Out of all of the dresses in the world, why did Charlie XCX decide to wear one that looks like a paper bag?
BEST: Zara Larrson
We're lusting over Zara's pink hair and embellished bodysuit, proving that a dress isn't the only option for a red carpet event
WORST: Natalia Vodianova
There isn't one good thing about this dress. Sorry, not sorry.
WORST: Louisa Johnson
The corset, the flares, the feathered ends. This is a fashion disaster if we've ever seen one.
BEST: Holly Willoughby
Holly Willoughby's sparkly mini reminds us of Heidi Klum's Grammy's outfit - and we love it just as much.
WORST: Nicole Scherzinger
Tell us Nicole, exactly what inspired you to wear matching sparkly thigh high boots and a blazer? This outfit will go down in history as one of Nicole's worst choices ever.
WORST: Myleene Klass
Without the belt and floral head piece, this could have worked. Could have.
WORST: Stacey Solomon
It's the Brit Awards Stacey, not afternoon tea.
WORST: Billie JD Porter
This takes the 'nightwear as daywear' trend to a whole other level.
WORST: Caroline Flack
We're pretty sure we saw teenagers wearing this at Drake's Dublin concert.
BEST: Zara Martin
This outfit shouldn't work, but somehow it does.
WORST: Laura Jackson
The tinfoil look is never going to catch on, okay Laura Jackson?
