I will start by saying that at first i bough this jacket in size Small, following diferent reviews mentioning that it runs large, and it probably does but that depends on your physique. I'm 1.70 m (5'5) tall and 75 kg (165 lb). I have always bought size in mediums but this time i chose first small. I would say small size fits me well, kind of fitted, but unless i will stay just standing, without moving, i started to fell it not so good, when i try to drive my car or try to move my arms i feel very restrianed. So i decided to sell it to a relative younger and go for the medium. At first was a little bit concerned about size M will make a big difference and i would start having the opposite issue, a baggy jacket. For my surprise, when i received the M jacket, it fit me very well, the difrerence with the small was just enough to eliminate all the issues i had at first with the Small one. I would say overall, the Medium increases 1" inch to shoulders/chest/waist, and length from shoulder to waist; as for the arms length i would size half inch is added, and that's good because this jacket has kind of large arms, which i noticed even on the small one, but i think this is on purpose, since this jacket style is kind of motorcycle jacket, so when you extend your arms it gives you enough to avoid expose your forearms. So in the end, medium will fits you like a globe if you're around 1.65 to 1.75 m tall and, depending of how you like the fit, from 70 to 80 kg. Small size i would say its more for people around 1.55 to 1.65 m and 60 to 70 kg. This jacket has some kind of fitted style, so take this in consideration if you have a big belly. it's not a baggy cut. Now, talking about the quality...it's great!! Even is not real leather, the look of this jacket is very nice, it doesn't look like plastic as i have seen on other jackets on local stores (hello Levi's, Merona and Arizona). Faux leather is thick and it feels like leather to the touch, jacket is "heavy" and by saying this im not complaining, im just saying that this is a good feature. Color is very nice, is some antique/rustic brown, not a solid color. I have received many complaints about it in general. Jacket has internal cloth liner, that makes this jacket more warm, also it has internal chest pockets on both sides, so you have additional room for carry your phone or any item. Also, as you can see on the pictures this jacket features a detachable hood that you can use it whenever you want. Finally: Pros: Color, material, cut, look,price Cons: This is just something i would like, not something bad but i would prefer the hat to be black color instead of grey. The pictures i'm posting are from the Medium size. I didn't have chance to take pictures to the small one. I hope these help you to get your size at first time. Sorry about the illumination, they don't make justice to the color but will show measurements for your reference.
