For blazers, fit is more important than the brand, fabric or workmanship. The blazers must help you have a high spirit. It will be restrictive if the blazer is tight. Conversely, it will be soulless. So it would be better for blazers to be made exactly for you except the person whose figure can comparable to the clothes rack. Too tight or too loose, neither of them can meet the requirements of blazer dress code. I will tell you what kind of blazer is fitted. First, the clothe shoulders should be slightly wider than shoulders 0.5-1.5cm. Second, you can just put down a fist in front of your chest after buttoning up. Third, the hem is located between your thumbs when hands naturally drooping. Four, the end of sleeves should be located between the wrists and hand thumb. Overall, being refreshing is the first place.
