David Beckham and his brood turned out in force to support wife Victoria's runway show at New York Fashion Week on Sunday.

Sons Brooklyn, 14, Romeo, 11, Cruz, 8, looked elegant with slicked back hair just like their suited father, David, bouncing two-year-old Harper on his knee, while Vogue fashion queen Anna Wintour sat nearby.

Wintour, editor-in-chief of American Vogue and artistic director of Conde Nast, has for decades been the most powerful arbiter of style in the global fashion industry.

Held in a Cafe Rouge in Manhattan, 39-year-old Victoria Beckham's show was one of the most crowded on the fourth day of the week that kicks off the global 2014 fall/winter season.

In immaculate white surroundings, she showcased an elegant and sophisticated collection dominated by floor-length dresses, pleats, spectacular naked backs and careful structuring.

Gold chains picked out details here and there, while black and white were the dominant colors.

Beckham, who unveiled her first collection in 2008, has won plaudits for her attention to detail and beautifully crafted, feminine outfits that can be worn during the day and evening.

She explained that her fall/winter 2014 collection had more design details and a greater focus on evening wear.

"Each season I can push my fashion story a little bit more. Each season the more people understand me and understand my brand," she said.

"I love the long beautiful feminine skirts, with a more masculine trouser underneath it. I love long lean silhouettes and the fact that they are beautifully structured," she added.
