Hi everybody. First of all, thank you everybody who stop by this thread. Let's make it straight forward. I'm a short guy, only 5ft3, but kinda muscular with 140 pound and 38 inches around the chest. As I don't live in the US or Canada, it's very difficult for me to buy some quality shirts and jackets online because if it doesn't fit me, too big on me, I can not return it to the US store because the shopping rate is costy and long time to return to the store in the US. So when I checked at some online store like Hugoboss,Gap,kenneth cole, Ralph Lauren.. etc. my size is perfectly fit size Small. But what confuses me the most is that the model in those photos are more than 6ft and only wear size M. That makes me think size S is would be too big for me. So If anyone who have the same build with me and has experience buy clothes from those brands please give me some advice. Because this is my first time here, so I don't know whether this post is approriate in this forum or not, please forgive me if I posted in a wrong one. Thank you so much.
