Relevant to the topic but slightly askew of it, I don't wear a smoking jacket as such, but when I'm smoking I wear clothes that I know I will not use when visiting, going to meetings or business arrangements. I have a set of trousers and jumpers that I call my house/garden and smoking gear. These suffice for smoking and can easily be thrown in the wash after a couple or days. I also wear, particularly in colder seasons, a sleeveless body warmer with plenty of pockets that can carry all the accessories from lighters to tampers, pipes to pouches! All this saves on using up decent clothing and stops it reeking of stale tobacco odours. I think that, for myself, a smoking jacket would be a tad too indulgent. I already have my own, as it were!
