I like the fit, the material, the overall look but can't understand why I was given instructions to order my regular size when almost all the reviews I read said the advertised sizes were all too large. I took the advice of the reviews, ordered a 40 short instead of a 42 regular and got the good fit.
I wear 39 Reg blazers. Given prior reviews, I contacted customer support, who volunteered back and sleeve measurements. Based on those numbers, I ordered a 36 short, which fits perfectly. The jacket is great for the price. I plan to order another jacket or two. It does seem crazy to have to go through this trouble to get the right size, however.
This is a great blazer. Great value and great material considering the price. The only "issue" is the size. I ususally wear 42 regular and I ordered 40 short. Even with 20 short, I think the sleeves 1/2 inch longer but it is ok.
