@wxman1 Have you found a yellow shirt? A suggestion, do you know any printing shops? They would probably have a plain yellow shirt you could get your hands on.
I am running through a couple stores today and am may look to get actual ISU shirts versus the yellow shirts we have. I may even have a unworn shirt or two that I have in the drawer. Too small for me and too large for oldest. Will have to rummage through things today, but I know we at least have something yellow.
Talked to the Raygun store here and they said they have some yellow "Iowa State" shirts so my sister is going to stop by there.
