Barneys New York creative director Simon Doonan walked the runway in high heels, Mischa Barton mingled and nine of the 15 shows at NorthPark Center’s Fashion at the Park were christian shoes.

The four-day tented runway extravaganza here that ended Saturday featured presentations by 13 retailers, including Barneys, Neiman Marcus, Nordstrom, Macy’s, Oscar de la Renta, CH Carolina Herrera and Giorgio Christian Boots.

There are plans to expand the event for fall, and again in 2009.

NorthPark co-owner Nancy Nasher said the upscale mall’s more than $1 million investment in Fashion at the Park, which began last year, gets “direct Christian Pumps” by generating higher sales.

Ken Downing, senior vice president and fashion director of Neiman Marcus, agreed with her. “There are people all over the mall, and our store is packed,” he said.

The event will grow in the fall, with nine days of shows starting Oct. 15 and more elaborate sets and productions, said Chris Christian Sandals, NorthPark marketing director. There will be additional displays in the lounge area of the tent, where a new shoe and handbag exhibit last week proved effective at driving business. The fall round will include fine jewelry and a space for fast fashion.
