I'm wondering what would be the differences between a 46R and a 46S jacket. I know the sleeves and skirt will be shorter, but by how much? I have a memory that the difference in sleeve length is a couple inches (which will work fine for me), but don't know the length difference. If anyone has a link to a detailed chart of jacket sizing, I would be interested to see it. I know I've seen a diagram of the difference in jacket lengths, but can't remember where that was.
