Stylefile: Blake Lively.

Blake Lively. Once upon a time she was that gorgeous blonde with the impossibly long legs who played Serena Van der Woodsen on Gossip Girl. Fast forward to 2011 and she still is that gorgeous blonde with the impossibly long legs who plays Serena on Gossip Girl, but she certainly has evolved beyond that. With roles in both the critically acclaimed, The Town, and the impending comic book blockbuster, Green Lantern, Lively has officially graduated to Hollywood starlet, but some of her most admired moves have been those offscreen.

Over the past year Lively made some serious strides stylewise. Labelled, “The bombshell” by US Vogue, she has added a dose of boldness and sophisticated sex appeal to her look that has proved undeniable to the powers that be, including fashion’s annointed king and queen, Karl Lagerfeld and Anna Wintour. Their nods of approval have landed Lively the coveted Vogue’s Best Dressed title for 2010, front row billing at New York and Paris fashion week showings, and the honour of representing Chanel’s new “Mademoiselle” handbag line.

In 2011, the self-styled Miss Blake Lively is laden with fashion cred, due to her willingness to be just a little unconventional, her penchant for bold colours, daring silhouettes and embellished and textured fabrics, and her loyalty to sky-high Louboutins.
