I feel the size chart from Haband is mostly useless for this Blazer, because it shows the Blazer in numerical sizes like 48, 50, 52 and so on however the size chart shoes sizes in XL or XXL and so on.
How does one know what size the Blazer really is? What is a 52 size Blazer in XL sizes?
BEST ANSWER: The numerical sizes are the number of inches around the shoulders. The "XL" will mean extra long length - Which will probably be for someone 6'2" or taller. I am 6' weigh 220 with a 40' waist.. I bought this blazer in size 48 regular and it fits perfect. A size 52 in XL would be for a very big and tall guy. To get your jacket size, get a tape measure and measure completely around your chest and shoulders. The number of inches will be your jacket size. If you are 5'9" to about 6' 1", you are probably OK with regular length... If shorter get "short", if taller, get "long" or extra long.
