Corral West Ranchwear is planning to open more work wear depots in upper Midwest US after opening its first in Milwaukee last autumn, it was reported in the press.

Chief executive Les Ball told the University of Wyoming College of Business that the company was pursuing the direction of the work wear market after cracking the Western wear market, Wyoming Tribune-Eagle reported.

After carrying out research, Corral officials found that there was no single upper Midwest or Northeast retailer apparently geared toward blue-collar workers.

According to Ball, work wear has the potential to be a $12bn-a-year business.

Private equity firm Sage Group has been providing financial backing for Corral's new venture.
