Actress Amanda Seyfried is busily promoting her new film, "Les Miserables," slated to open Christmas Day. The actress, who plays Cosette in the film, is treating fans to a whirlwind fashion tour as she walks red carpets around the globe.

Over the years, we watched Seyfried go from a vapid blond in "Mean Girls" to leading lady in "In Time" and "Red Riding Hood." She has also made quite the style transition over the years. Once a teen in boot-cut jeans and spaghetti straps, the actress now walks the red carpet in sophisticated gowns.

Seyfried chose a ruffle-hemmed Balenciaga gown at the "Les Miserables" premiere in London, a gold Alexander McQueen bustier for the film’s New York premiere and a Misha Nonoo spring 2013 white dress with clear panel hem at a luncheon in New York City.

The actress recently visited the Hollywood Walk of Fame for costar Hugh Jackman’s star ceremony wearing a Burberry belted trench, Heroine leather tote by Alexander McQueen, tights, suede booties and some killer red tinted shades. She looked sophisticated, classic and every bit the movie star in stylish winter essentials.

For a similar trench with piping, try the Merona water repellent classic trench coat in khaki with black piping from Target.com for $37.49. Suede booties come in handy for several seasons. Try the Lauren Tiara suede platform bootie for $74.99 from RalphLauren.com for a high heel and the tasseled zip booties with a wooden heel from Forever 21 for $22.96 for something a little shorter.

Seyfried’s tote bag and retro sunglasses are fun accessories for her winter wear. For a similar bag, try the Urban Expressions flare bag in black from Misskl.com for $76 or the Ivanka Trump crystal top handle satchel handbag from Zappos.com for $175. For some shades, get the Quay retro sunglasses for $38 or the A.J. Morgan front row sunglasses for $24, both from Nordstrom.com.
