OK, this is serves as a good reference for something I've been wondering: Are the sleeves on Fred's jacket the right length (i.e., he needs a shirt with longer sleeves), or should the jacket sleeves be shortened? I assume the latter, but iDunno.
I think the jacket sleeves should be shortened just a bit - about 1/2". And his shirt sleeves should be exactly as long as his jacket sleeve is currently.
The 'general rule' for jacket sleeves that I've always used is that they should hit dead center on the protrusion of the wrist bone.
