Sarah Jessica Parker’s Lily dress becomes Hollywood trendsetter

The Lily wedding dress, which Sarah Jessica Parker wore in the Sex and the City’ movie, has become a rage in Hollywood.

Designed by Vivienne Westwood, the dress is wooing Hollywood's most glamorous with its ultra-slimming shape. And the secret behind the popularity of the creation is — a structured corset topped with an exaggerated sweetheart bust.

"The top is her signature detail, but the silhouettes can be quite different; there's a flute dress or a frilly '50s-inspired A-line," the New York Daily News quoted a Westwood rep as saying.

The original Lily came to fame after style icon Sarah wore a wedding-gown version in 2008's Sex and the City movie.

Immediately after the film’s release, the shorter, nonbridal Lily - which goes for $9,875 - sold out worldwide.

And thus, Westwood continued to create new versions.

And recently, in her spring 2010 line, she featured a fitted, slate-gray ­version that was sported by Emma Thompson at a movie premiere in London last month.

Oscar winner Sandra Bullock rocked a shimmery champagne version of the dress to the People's Choice Awards and instantly earned rave reviews.

Songstress Leona Lewis went edgy with a patent-leather mini-version of the dress at the American Music Awards.

Even budget-friendly retailers, like Topshop and Forever 21, are stocking the sweetheart-corset trend.

"The top [of the Lily] is the common feature which is flattering for all silhouettes," added the Westwood rep.
