I don't see the one Dom wore. I've never been to a Wembley gig but I slept at Wembley last November when I won a short cruise on the Thames for Coldplay Christmas song.
OoS all the way haha. I'll probably just wear one of my older T's. I do fancy getting some green skinnys, like the ones Dam wore at the 2007 Wembley gig.
You could design a nice tee-shirt yourself, it would come out cheaper. That's the way I've made mine with a transfer, to choose a great picture and print it on the transfer. There are several transfers in the box so you can make several nice tee-shirts that you buy white for instance.
I've been thinking about making a special T-Shirt too. Something on the lines with the OoS album cover. I know a few other people who are doing it, would be pretty cool.
