I recently bought a BMW Santiago jacket, which according to the sizing chart, I would need a Euro size 50-52 since I wear a US 40-42 suit coat. When I got to trying them on, turned out the Euro 46 fit me just right. I mentioned this to a store employee, who said BMW products are made in various parts of the world, and as a result vary in size even if they are labled as being the same size. Since they are made for the same company I wouldn't think that would be an issuue, but that's what I was told.
Oddly enough, I have a Vanson jacket that is sized US 44, so Euro 54 I guess.
Regardless, my two cents is don't buy any gear unless you've had the opportunity to try it on first.
Good luck on some new gear.
