True Religion Apparel Inc. has appointed Lynne Koplin as president of the company, effective immediately.

Koplin, who joined the Vernon apparel maker and retailer in January 2010 as chief operating officer, succeeds Mike Egeck, who has resigned from the company to pursue other opportunities.

Prior to joining True Religion, Koplin was women’s division president at Tommy Bahama, a subsidiary of Oxford Industries, and before that worked for a variety of apparel and retail companies.

“The decision to move on from True Religion has been a hard one to make,” Egeck said in a statement late Thursday. “I think highly of the company and its future prospects, and I have enjoyed my time working with this team.”

Shares on Friday were up 9 cents, or less than 1 percent, to $27.80 in midday trading on the Nasdaq.
