I'm just trying to understand how an adult can, or would even want to, stay so thin.
In high school, I was 6'3" and 135 lbs. Over the next 27 years or so, my weight crept up to 160 and now, after 3 years of dedicated weightlifting and eating, I weigh 185 lbs. So I understand the OP's dilemma.
To the OP: I have a peacoat from Sterlingwear in size 40L. You might require something like a 38L and some extra tailoring. A duffle coat in a similar size might also be good.
If you don't already have one, find a good alterations tailor for shirts and jackets.
