Try BLK directly, they are selling green lantern jersey's on their website in Australia, we just ordered some over Christmas, they might be able to help you out..

Yeah they're all sold out so the only hope is a trade. That's the reason I ended up with the wrong size to begin with. A thoughtful gift all the same though.

There's none left in shops or online so I doubt that's an option

Can you not get hold of the receipt and exchange it for the right size?

Hey everyone. I was given a great Christmas gift of the Connacht Green lantern jersey this year but I was given a large boys jersey (size 14) and I would need a medium man's shirt. Does anyone out there have a shirt which they would need to trade for a smaller size? I don't want to put this up on DoneDeal but at present it's not good to me and it's a great collectors item for a Connacht fan!
