From tough tomboy to punk-rock princess to freshly minted glamour girl, Kristen Stewart 's style has been a hot topic among advocates, adversaries, and ambivalent audiences for over a decade. While the leading lady has made a few questionable choices — who hasn't? — we applaud her ability to blend her signature no-fuss style with high-fashion haute couture.
Kristen's social calendar is jam-packed with exclusive events, but having Balenciaga, Chanel, and Zuhair Murad, just to name a few, on speed dial gives Stewart free rein to select the most heart-stopping creations, ensuring her turn on the red carpet  never wavers.
In honor of Kristen's 26th birthday we're taking a look back at the ravishing red carpet moments that have earned Stewart style icon status.
