The 28-year-old lilac-haired presenter, accepting the accolade from Radio 1 Breakfast Show host Nick Grimshaw, paid tribute to her formerly eclectic sense of style, reported Daily Mail.
"I used to look like crap. I never thought I'd get a style award. Cosmo putting me on their cover a couple of years ago did wonders for my self-esteem," Osbourne said.
Showing off her trim figure in a form-fitting floral print silver and lilac silk dress, the 'Fashion Police' host looked simply stunning at the awards.
While the pretty frock accentuated Kelly's slim waist, the daughter of Ozzy and Kelly Osbourne added height to her frame with a pair of towering peep-toe stilettos, while she kept her lilac curls swept to one side.
