Hi fellow Assassins,
If you haven't see yet, it is possible to buy Desmond T shirt since december. Where? Ubiplay. I think it is a must have for those who want to cosplay or are just making collection (like me). And now they have updated the T-shirt for a new version that is exacly the same Desmond wears.Just go get it:
