Good evening gentlemen, thank you all so much for teaching me about how a jacket should fit around the waist! I really learned a lot!
I have been looking at more videos about the fit of suit and sports jackets, and I see that many of them mention only how they should look on the outside, and less about how they should feel around the shoulder area.
Could I ask under the conditions that the jacket fit looks right on the outside, what is the range of motion of the shoulders? Should one be able to
- Flex the shoulder blades front and back
- Raise up their arm freely (provided that the arm holes are of a correct size)
- Not feel any tightness in any region at all?
Is it absolutely impossible that a allow a similar range of motion to a T-shirt or dress shirt?
