Obviously this can be fixed to some extent, but some jackets have too much space and it's tough to bring them in sufficiently.
The biggest problem area is in the upper arms, since tightness there really restricts movement. To accommodate my upper arms, I have to get jackets with wider shoulders than I might otherwise prefer (the pads extend a little past my actual shoulders). Is it proper to fit shoulder pads wide enough to cover the upper arms when one's upper arms extend out wider than one's actual shoulders? What is the ideal, say in the case of MTM? Can wide upper arms be successfully accommodated merely by increasing sleeve size, or do the jacket shoulders have to be extended out a little bit?
if you go with m2m or custom made, this can be done. but you must discuss it with the tailor.
at the start you should wear a suit you have that shows the problem.
that way he can see just where the adjustments are needed.
