Well have been SO upset about these tiny holes showing up in brand new shirts. It has been driving me crazy. I though it was the seat belt in the car, but have been religiously pulling my shirt over the top of the belt. Thought it could be pants snap, but have worn so many different kinds and still get the hole. Also have worn a tank underneath and just today found a hole in a SWEATSHIRT that I had worn once, over the top of a tank and with seat belt underneath. HELP this is costing a fortune!
