I bought this from someone a few years back, wore it once and forgot about it. It's in perfect condition aside from a few scuffs on the shoes. I was told it was a UK size 12 when I bought it but it actually wasn't as big on me as I thought, so I'd say it's more like a 10. The shoes are a UK 5 and have plenty of room width-wise and the gloves are a medium.
The price: £20 plus about £8 postage within the UK (I'm willing to post abroad but the postage would be more) and I'll accept Paypal or cheque. Send me a note if you're interested!

(I do also have a wooden keyblade if you're interested, which I'd sell for £10 once I've re-attached the handle, but I reckon I could only post that in the UK because it'd be fragile and cost more to post)
