But, I want it to fit "properly" whatever that means. Any hints on what I should look for, focus on to determine if fit is ok (button pulling, etc.)?
Button-pulling is bad. Try raising your arms outward from the sides and then bringing them forward until they meet in front of you. If this feel tight, then the jacket probably is.
It sounds to me like you're a 44 (or a 43?). Pictures would help. Roomy in the chest is a bit subjective, and it's not clear what standard you are applying.
A little bit off-topic, but I had a debate this morning with one of the helpers at Barney's Warehouse sale, where we had a debate over whether a 56 European was more like a 44 than a 46 (the suit was labeled 46R). In the end, he allowed that the 46 was a mislabeling in this case, but seemed pretty confident that a 56 was generally equivalent to a US 46, and I could not disabuse him of this belief.
