The Shake It Up star has a wardrobe full of feminine frocks, but this time she opted for a stunning metallic two-piece by Zadig & Voltaire.
Bella let her short suit do all the talking by adding a plain black vest by BCBG Max Azria.
She also rocked a pretty impressive pair of strappy heels by Rene Caovilla, which featured gold snakes running up the front plus silver glittery heels. Fancy!
The starlet paired her head-turning ensemble with gold jewellery while rocking a small mirrored clutch by ALDO (a high street buy - hooray!)
And as always Bella wowed on the beauty front too, decorating her peepers with shimmery green eyeshadow while sweeping her locks into an elegant updo.
Top marks again, Bella!
Oh, and Ed Westwick was at the Young Hollywood bash too, looking ridiculously hot in a dapper suit. Swoon...
