Hi again br> So the jacket lengths have been going up and up lately. I've heard many different methods and formulas for jacket length. 1. take your height in inches and divide by two. I am 5'7" or 67 inches. That would be a jacket of at least 33 inches which appears way too long. What length would be ideal for me? 2. Always cover your bum. 3. The length should not exceed the base of the thumb to the first knuckle of the Thumb. (ie. From your first metacarpal joint to your proximal phalangeal joint). 4. Certain designers for example Tom Ford's Windsor jacket seems to be longer than their Shelton jacket ( in the same size). Many criticized Daniel Craig's jackets in the James Bond movies because they appear to be too short. I spoke with a sales associate at a Tom Ford store in Miami who told me that they were trying to achieve a balance/ proper proportion secondary to his height. "Technically, the jacket length should be approximately half the height of the distance between the point that is the base of your neck down to the ground. " 5. Cupped fingers method What method or formula do you recommend ?
