thoughts on Costume National pea coat

Hi all, been lurking for a while, finally have a question to ask.

I've lost a lot of weight since last spring and so none of my fall clothes fit me (which is kind of a blessing, most of it was terrible). I'm a tad under 6'4 and weigh 165, with a slender build, long arms and legs (even relative to my height). And no ass. So I like a trim fit. I have read that Costume National is both trim and fits long in the arms, and so I was thinking about getting this pea coat:

Thoughts? Is it worth the $420 that is being asked? I'm also not sure if a 50 will be too large as my chest is more like a 48, and I feel like the sizing takes into account the fact that you'll be wearing clothes underneath. (But I have asked for measurements.) Thanks in advance. This forum is a great resource.

OK thanks. Guess I will have to keep looking.

I believe they are made in China. Not great but not a dealbreaker, and unfortunately I'm on a budget. How do you find the quality of your CNC stuff?

Actually it looks like some of the CNC stuff is made in Italy
