Loop Jean Co., a locally owned business, is expanding to include The Robert Graham Shop men's clothing line.

A grand-opening celebration will be held today at noon until 7 p.m. at the store in Casas Adobes Plaza, at 7047 N. Oracle Road. Ten percent of the proceeds from any Robert Graham purchase will be donated to the Angel Charity for Children Inc.

Since its opening in 2008, Loop Jean Co. has seen a steady increase in business, said owner Ted Greve. To meet demand, the company is expanding to include the separate shop that offers Robert Graham clothes and accessories, he said.

"We took over a space that became available next to us," Greve said.

The new store is located next to Loop Jean Co.
