Regarding jacket length, based on my full bespoke suits, it appears that I could go a little shorter.
Here's some bespoke jackets I have for comparison:
Two WW Chan suits: These are definitely shorter.
A suit by Raphael: Maybe just a little shorter, but not much. (Hard to tell because of the pose.)
You definitely are a hard fit, but that Raphael is absolutely fantastic.
Love the A. Lange, too.
