Bel won the competition, which launched last month, after being shortlisted to the last three, from more than 130 entries.
The competition, in association with Campaign and sponsored by Next, formed part of the annual Elle Style Awards.
As her prize, Bel will receive two VIP tickets to the exclusive and celeb-studded Elle Style Awards this evening, as well as a night’s stay at The Savoy hotel in London.
Elle’s editor-in-chief, Lorraine Candy, fashion director, Marie Curtis, and Campaign's editor Danny Rogers judged the competition.
Bel was shortlisted along with digital planner/buyer Anne Claire Paton from Zenith and Sarah Malek, a media assistant from MEC.
She was chosen for her androgynous look, combining ready tailored trousers with a casual sweartshirt, which the judges said was "smart and very on trend".
