I would like to ask about the size in cm of the [i]Bungie 30th Anniversary Pullover Hoodie[/i], since I am having problems with the inches to be able to have an exact measurement and make the purchase. I would also like to know if in case I make a mistake in the size I could change it for another of greater or lesser size. Thank you very much. (っ ͡• ͜ʖ ͡•)っ🎔
