the All I Want Is U2 occasionally has an 'Edge's Shirts' thread in it.
There was a thread in Everything You Know Is Wrong about Edge's Music Rising shirt from the Grammy's....but none of us know where to get one (not even on the MR website).
As for his cool numbers shirts from the Elevation Tour, someone a long time ago posted a link to a company that makes ones like it---you can tell them a number & they'll put the glitter & sequins on---but they charge like $130 or something for a t-shirt. I've been tempted to make one for myself, but it seems like too much effort. I might instead go to a thrift store, look for a cheap black leather jacket & sew a red star on it like B's from the last tour.....we'll see...
