Cefai i saw someone wearing that illuminated shirt in Gatecrashers in Birmingham, been racking my brain for months how you wash it & still keeps working!... almost embarrassed to state the obvious, he certainly stood out!

I used to have some humorous ones, think they are from one of these:

Music t-shirts, band t-shirts, movie t-shirts, funny t-shirts, vintage t-shirts, music tshirts, band tshirts, movie tshirts, funny tshirts, vintage tshirts - TshirtGrill

when it's cold i put a bright shirt sometimes under a button shirt, if it has a pic on it, quite frequently women do ask what it says etc, so i guess it works.
