WORST: Gigi Hadid
The co-hostess with the mostess was swamped in this Roberto Cavalli semi-sheer lace dress. She redeemed herself later in the night with quick changes though...
BEST: Lady Gaga
This Brandon Maxwell white pantsuit with a plunging neckline is peak Lady Gaga. And it's perfect.
BEST: Selena Gomez
The girl knows how to make a comeback. In her first post-rehab appearance, Selena stunned in a red Prada ballgown.
BEST: Renee Bargh
Fun, flirty and fashionable. This tv presenter's dress ticks all the boxes.
BEST: Janelle Monae
Bold and beautiful.
WORST: Heidi Klum
There are no words to describe this gold parachute style suit. She definitely won't be cloning this look.
BEST: Hailee Steinfeld
Hailee oozes sex appeal int his sequin dress.
WORST: Ariana Grande
The trousers are too 2003 and I can't help but feel I've seen this bra top 100 times before.
No one can pull off a white leather jumpsuit, even with that figure.
WORST: Hannah Davis
The purple is tacky and I think we're all over the sheer trend now.
WORST: Kat Graham
From the top up, it's perfect, the bottom half is ill-fitting and looks uncomfortable.
She wouldn't look out of place in a modern day Moulin Rouge, but this monochrome can-can dress somehow works - not to mention it's maternity fashion.
WORST: Julianne Hough
Between the bad wig and powder blue pleather, nothing is saving Julianne Hough's outfit.
WORST: Bella Thorne
A bra top I can get on board with, a bra masquerading as a top isn't stylish.
WORST: Rebecca Romijn
The full skirt is perfection, but the sheer top doesn't' complement this look in any way and even Rebecca's world-famous figure can't save it.
WORST: Chrissy Teigen
Chrissy really just went for it. All of it.
WORST: Milla Jovovich
If it actually fit, this look would be gothic glam goals. But it doesn't.
WORST: Karlie Kloss
This Versace number is a bold choice that didn't pay off. If Karlie can't pull this off, no one can.
WORST: Olivia Munn
Olivia forgot the rest of her outfit at home.
WORST: Lauren Giraldo
YouTuber Lauren looks like she's about to take off at any moment.
