just spotted these on the Tesco clothing website
they have all 4 houses, including a platform 9 3/4 shirt which isn't as good IMO
great price for HP merchandise and they look really good
would make a great christmas gift
they are men's shirts but who cares?!
ordered myself one :D (Gryffindor of course)
links in first comment for each shirt
Update: Hufflepuff + Gryffindor back in stock !
Gryffindor + Slytherin now available in kids sizes 4-11
