Runs small.  Serviceable uniform shirts for a small private security team.  These are professional uniform shirts, and when coupled with hardware e.g., chevrons, badge, your people will be easily visible.  Recommend you size up from your normal size for a standard fit.  Not the best option for hot, humid weather due to fabric (recommend polo shirts), but for Spring, Fall and Winter, these uniform shirts are excellent.  I contacted seller to group my order into one shipment and they accommodated me.  I will purchase from this seller again.
