I bought my last Wasps shirt back when we last won the Heiny - A black one with Magners across the front - and I've worn it ever since. In some ways it is nice to see other people with old shirts on at games, and just around and about. But I haven't really seen one I liked enough to replace old faithful. But I said that I would buy a new one regardless of whether I liked them when we next won some silverware.
I'm really hoping that I'll be online buying a new shirt later today...
(Disclaimer - I do have a blue shirt signed by the whole squad which I won't wear not only because of the signatures, but because it is BLUE)
