the sizing is really weird. I ordered a 15 and a half (collar) as I usually do with other makers ... yes the collar size is perfect, but unlike any other 15+half shirt I own, the shirt is really over-sized and the sleeves are way too long!! Luckily it is pure linen, so hot-washing it 3 times shrunk it down to size. I would like to buy more shirts like this, but I don't need the surprises or the extra work!
