Not sure this will be of any help, but here goes. Would say the same to anyone collecting jackets, especially someone with some gray on their head. Why not think toward the future and buy a bit on the bigger side to allow for "growth" as you age? Even if your weight doesn't change, gravity does interesting things to our bodies as we age that can radically change fit. There are so many things that can cause us to put on weight as we grow older...many out of our control, ie health issues. It would be a shame to have a "perfect" collection of jackets today become unwearable in one fell swoop because one cut things so close from a fit perspective.
