The jacket is so awesome. If you want an oversize look, you should definitely size up (I usually wear xs, but ordered M).
it is a modest oversized, but I think if I wanted a longer and fully oversized look I would have went with a M.
I typically wear small/medium, and was afraid medium would be too big, but, if you want a very oversized look, medium is the go! the small is not a snug fit by any means, but I feel sits just below/at my bum, where as I feel like a real oversized vibe looks best sitting well below bum, just my thoughts!
I'm not sure if this jacket is real as there is no proof on atag but if is what I needed. Large enough to wear over my sweat shirts and is cute enough to just wear. It is really really large
