No idea - but I'm very jealous!
Can't wait to get mine (though it'll be quite a wait as we don't have one all that near). Well done Laudy 
Wear it with pride!
ps I always go up a size anyway as I like a bit of bagginess! And since they have the decency to have proper sizes instead of just S,M,L etc then there's not usually all that much difference as they go up - not that'd stop you running in it anyway!
