What is FREE SIZE?!?

I'm thinking about getting this One Piece t-shirt from ncsx since it's only $21.  The size though is FREE SIZE and I dunno what the hell that means!

I see it's 65cm vertically but is that really enough information to figure out if it fits?  I sorta measured my Threadless small t-shirt and that seems 60cm and is just about the right length for me.  Hmmmmm...

I have that Gundam Unicorn shirt that came with last month's Gundam Ace magazine. It's a free size shirt, and it's slightly larger than an American men's small. Fits me pretty well, but it's a little wider than I'd prefer.

Thanks for the info

I actually checked threadless's site and the men's S there is 69.9cm, so this is actually a little shorter so length-wise it's just right for me.  Width might be a little big going by your description, but ehhh...it's $21.  I'll give it a shot

It's about the size of an American "M" -- maybe a tiny bit smaller. It's pretty hard to find FREE SIZE items in Japan lately, as Japanese youths are growing larger on average each year. Anymore, it's pretty easy to find not only "LL" (American L equivalent) but even US sizes of L and XL here. I just bagged a sweet Pac-Man shirt at UNIQLO.
