Size Check for Barbour Coat

I’ve been curious about getting a Barbour Beaufort, and ended up stumbling into one in a second hand store. I think it’s a size or two too large? Couldnt find a size label on the coat, but the stores tag said 44, and Im usually a 38. I’m not sure if that’s true since it doesn’t look terrible, but I kind of wanted it loose anyway. Thoughts on how this should fit if I go back for it?
