you are both right on the money... Went to the tailor and he is taking care of the jacket no charge, since I'm a good customer and he didn't take care of it previously.
Also, I've come to realize EVERY shirt sleeve I have is an inch too long! Never realized it before, as this is the first jacket I've had that is the proper length in the sleeve. All my shirts when I'm standing are almost an inch too long, maybe 3/4 of an inch.
I'm pretty new to all of this, but reading this forum has been a HUGE help.
All that said, he is letting out the back a bit and taking the material out of the shoulders... Jason is correct in stating that shoulders are the HARDEST part.
Personally, a 32 inch sleeve length fits me perfectly how I like it, which is when unbuttoned, the cuff sits around 3/4" below the break of my wrist. That way when bending my arm, the shirt tends to rise proportionally with the jacket, rather than leaving 2-3 inches of sleeve showing.
