Heroes' Hayden Panettiere, aka the newest It girl ingenue, may be young, but she’s already got an eye for fashion! Out and about in LA and NYC, Hayden seems to never be without her Express black leather bomber jacket (retails for only $198!) and Rebecca Minkoff Morning After bag (rebeccaminkoff.com). In New York, Hayden paired the Express leather topper with a pricey Herve Leger skirt, proving she has the fashion know-how to mix expensive designer labels with more affordable pieces (a rule of thumb used by the fashion elite). Back in LA, Hayden goes casual with girlie minidresses or jeans, a vintage tee and her two favorite pieces — from Express and Rebecca Minkoff, of course! If Hayden keeps this up, she’ll be a fashion hero in no time!
