Insider's Look at New York Fashion Week

New York recently wrapped up its annual Fashion Week -- signaling the end of a busy work week for many of New York's fashion magazine editors.

But what does a fashion editor do at Fashion Week?

Zanna Rassi, a senior fashion editor at Marie Claire magazine, helps the publication decide which pieces from the designers' spring 2010 collections may make the cut into the magazine. She shared what she found this year at Fashion Week on "The Early Show" Monday, from the runways to the parties.

Rassi said Fashion Week is where all designers flock to show their collections for the next season. She explained there are three components to Fashion Week: the backstage, the runway and the social part.

"Backstage is very important," she said. "It's somewhere I go and talk to the hair and makeup artists. It's also a place where I find the new models."

The actual runway show, Rassi said, is where she does the most work.

"This is where I'm looking at the clothes, and deciding which pieces are going to work for the Marie Claire reader," she said.

Designer Yigal Azrouel told Rassi his collection took about six months, beginning with fabric.

"Then viola!" he said.

Singer and designer Gwen Stefani told Rassi she started her collection with "a little African '80s inspiration."

Rassi also explored Alexander Wang's spring/summer show, hailed as one of the best at Fashion Week.

"He designs sloppy tees, tight skinny dresses, and these amazing killer heels," Rassi said.

Rassi asked Alexander Wang, "You're 25 years old and basically the hottest ticket in New York Fashion Week. How does that feel?"

Wang responded, "I feel very blessed. And to be in this position of living a dream."

Top designer Diane von Furstenberg said she supports Wang.

"I am his mentor," she said. "... I'm into what he does."

Fashion Week also includes many parties.

However, Rassi said, it's not all glitz and glamour.

"There is a lot of champagne drinking," she said, "but a lot of business is done at these events."
