About Me:5'10", about 130lb, usually wear size S in shirts and jackets, or size 36/38 in sports and suit coats.I ordered this jacket in size 38, ivory.This jacket fits my build a smidge on the big side.The quality of this jacket is obvious from the first look and feel of it. Nice material, not too heavy, but heavy enough to hold its own shape and not wrinkle up too easily.The cut is a basic cut. For me, I probably would really need a slim cut to fit me best. But, the cut is nice and looks good. The shoulders are a bit wide on me and the sleeves are *just* a tad long. Again, this isn't a knock on the jacket, just a reference for sizing for others.The two buttons are placed appropriately so they are useful and don't look odd when buttoned.This jacket is a welcomed addition to my collection and I look forward to wearing it.
