Neill Davis, chief financial officer and executive vice president of formal wear retailer Men's Wearhouse, has resigned from the company to join women's wear retailer Francesca's Holdings Corp as president.

Diana Wilson, who has served as chief accounting officer since 2003, will succeed Davis as interim CFO while the company searches for a replacement.

Wilson has most recently been involved with Men's Wearhouse's UK corporate apparel operations following the acquisition of Dimensions and Alexandra in August 2010.

"We are very fortunate to have both Diana and David available to assist the company as it carefully considers how best to fill the chief financial officer position on a permanent basis," said Doug Ewert, Men's Wearhouse president and CEO.

Kelly Dilts, vice president of finance and accounting, will become chief accounting officer.
