This Blazer is actually good. I ordered it a year ago and it is still holding up today! I like the material because it is not too thick and I can wear it to many occasions,the fabric feels comfortable!
I usually wear medium shirts and sports blazer. Due to the slim fit cut, I had to order a large. I'm 5'7" and 165ibs with a stocky build. It fits well and the sleeve length is about 1/4" longer, but that can be tailored.
