Hi, very interested in the Aero Highwayman, however, I'm a little concerned about getting the fit right. I'm 6'2" but a bit high-waisted, and so the waist of my trousers is a little higher. I'm inclined to go with a long vs a regular, however I'm then thinking a long might be, well, too long. I've noticed that the Highwayman comes down to the waist in the pictres I've seen. What are your thoughts on this? Also, my chest measures 42" but I'd be wearing a sweater underneath which could add some bulk so should I go up a size and order a size 44? Thanks.
