Can anyone tell me the name of a shop in edinburgh it is in west port next to the grmarket?

the shop is on the left hand side as you walk towards the grmarket not far from a pub with seats outside it sells unusual t shirts and what looked like second hand clothes from the seventies, i believe it had an wrought iron gate across the door when it was closed. The t shirt i'm looking for had a picture of the beatles with the words the rolling stones above it any ideas?
