At the Marc Jacobs show, the'70s-tastic, Jodie-Foster-in-"Taxi Driver" ensembles were an instant hit -- but it was a radiantly stunning new face, Melodie Monrose, that had the audience buzzing. Not only did the 18-year-old Wilhelmina model rock Marc Jacobs' runway, she also walked in almost every major show in New York -- and she's currently setting the fashion world ablaze at Paris Fashion Week. Not bad for her first season modeling! Discovered earlier this year in Martinique, the coltish beauty is quickly making a name for herself with her regal profile, flawless complexion and unforgettable cheekbones. Check out our favorite runway moments from this lovely newcomer.
