Hey, I'm new to this forum, so I'm not sure if I'm posting in the right section. My apologies if so. I just purchased a trenchcoat and I'm not sure about the size. It should be fitted at the chest, but with the top button open the fabric seems to pull the button at the chest area. I can do everything without problems, reaching down and lacing my shoes, sitting down etc. So it really comes down to the chest area... The size is 52, it indicates the chest is 43,5", my chest is between 40 and 41". I would greatly appreciate any opinions on this.
