Zappos.com sees apparel sales doubling in 2010 and expects apparel will exceed footwear within five years, Fred Mossler, SVP of merchandising, told Bloomberg. Apparel currently accounts for about 7% of sales.

“From a product standpoint, we’re just at the beginning of
a lot of opportunity. The clothing industry is at
least four times the size of the footwear market. We’re just
scratching the surface there,” said Mossler, a former Nordstrom exec.

Mossler also said Zappos fastest sellers are beauty items, handbags and housewares, such as pots and knives.

In the brief interview, Mossler said he expects consumer spending to pick up this holiday, and is increasing its inventory investments in brands such as Ugg, Dooney & Bourke, Stuart Weitzman, Patagonia
and North Face.

“We think the customer is going to come back and we want
to be there to service them,” Mossler said. “We’re making some
bets about some of our best products and brands.”

Amazon agreed to buy Zappos in July for about $888 million
