i'm usually a medium in most things but there were none available in this jacket, and i loved the looked of it. i read a couple of reviews, one saying the sizing may be a bit tight, so i plumped for the large and it's turned out fantastic. good length to it, especially the arms, fit perfect. i'm just worried i'll end up pulling one of the buttons off one night, drunk! but yea, i'd definitely go for the size up rather than down if you're desperately trying to order one and it's limited stock available. the jacket itself is extremely long (as i guess you'd expect with a parka) and fairly warm, although on a really cold day you're gonna want a scarf or maybe an additional jacket underneath it perhaps. bought it sheerly for the aesthetics though, and it looks very cool, so it's a 5* from me!
