New York Fashion Week wraps up

New York Fashion Week wraps up Thursday after eight days of previews for spring 2013.

The long week of fashion saw collections from seasoned designers as well as newcomers, including actress Katie Holmes who presented her line Holmes & Yang on Wednesday.

The celebrities who once lined the front rows of these seasonal previews in party dresses have increasingly made their way backstage into positions of power.

Among the designers that presented over Fashion Week included celebrities Avril Lavigne, Whitney Port and Rachel Zoe.

In addition to celebrity lines, seasoned veterans, including Michael Kors and Oscar de la Renta, showed collections on Wednesday.

Michael Kors' sunny disposition found a home in Southern California for the upcoming spring fashion season. He turned out an optimistic, cheerful and modernist collection that he said was inspired by the architecture, attitude and mostly the weather he enjoys every time he makes a trip to the West Coast.

"You could be sitting at the Beverly Hills Hotel, by the pool, and you could find this entire palette whether it's the palm green, the turquoise of the pool, the yellow of the sky - of the sun," he said in a backstage interview. "And I love all the architecture that we see whenever I go out to California. ... You're seeing a lot of that kind of geometry play into the collection here."

Stripes were strong, and he opened the show with a female model in a red-and-navy striped bodysuit with a zip-front navy skirt with a crisp white belt, while her male runway companion had on a green-and-navy striped pullover and striped pants. On later outfits Kors played with the proportion of the stripes, mixing thick and thin, and even horizontal and vertical.

Kors said he purposely included bright colors and fun details on clothes that, while technically for spring, get shipped in February.

At Oscar de la Renta, the designer went for a mix of modern while still maintaining his position as the godfather of uptown style, with latex and leather.
