It seems to have been a brand-name item, so I've removed the collar label. It looks cool from both the front and the back. The size, when laid flat, is approximately 50 cm across the chest under the arms and 67 cm in length. The fabric has some stretch, so if you want a snug fit, even I, with a waist of 95 cm, can wear it. So, I think someone who wears an L size could also wear it. It's not a knock-off.
