Just in time for Pittsburgh Fashion Week, there's a new mobile boutique on the block.

Earlier this month, Marissa Zimmerman, 31, of Monongahela took her shop on wheels, the Vintage Valet, out for its inaugural spin at the Perryopolis Flea Market. Fashionistas will be able to find it out and about during Fashion Week, including Tuesday at the pop-up fashion display in Market Square from 11 a.m. to 2 p.m.

"I've always loved fashion," Ms. Zimmerman said. Plus, she likes to travel, so she decided to combine the two. She came up with the idea about a year ago while a student at The Art Institute of Pittsburgh studying fashion and retail management.

"I just started looking on the Internet and realized, my gosh there are lots of these elsewhere, such as California, New York and Texas," she said.

Since early summer, three others have cropped up in Pittsburgh: Roadie, Style Truck and Broke Little Rich Girl. Ms. Zimmerman's truck offers contemporary women's clothing with a vintage twist, so expect to find lots of crocheted looks, lace, pleats and floral prints. About half of the apparel is made in America. Pieces range from about $20 to $55.

"So far, people really like it," Ms. Zimmerman said. "They look inside and say, 'Am I supposed to go in?' It's exciting to see people's reactions."
