Hi,
I bought a J.Crew Chesterfield J.Crew top coat (online, on sale) about two years ago final sale. Size small. It's been hanging nicely in my closet since, mainly because the fit is very slim. It does button - but snuggly. I can't imagine fitting a suit jacket underneath. I was considering trying to sell it on eBay.
But recently I noticed online at jcrew.com and in a GQ editorial that modern top coats are being shown on the models as very slim/snug. Am I outdated? PS, I'm 27/5'11'/170 lbs.
