I am looking to get either a 46 or 48 beaufort in olive. I have tried on both sizes and am still contemplating because I am losing weight, maybe 30 lbs or so to get to ideal weight. Right now, the 48 and sleeves are a good length and I can wear a layer or two comfortable under it right now. Not sure if that will be the 46 eventually, but the sleeves were short on me. I am 6'5" 270. Since this is a big investment, should I go with a 46 and tailor the sleeves and bottom or go with the 48?
