I've got about 18-20 shirts. Mostly BDs. I probably only have a handful of medium spread collars, and no french cuffs. I've got 23 shirts in my regular rotation: 1. 10 OCBDs (5 sold blue, 5 blue striped) 2. 12 spread collar, French cuff blue shirts (6 sold blue twill, 2 light blue striped poplin, 2 dark blue striped twill, 2 light blue checked poplin) 3. 1 spread collar, French cuff white poplin shirt. Do you regularly wear anything other than the OCBDs, though?
