Looks good CMcG. I don't have one yet, but it would be my choice for formal wear. I'm keeping my eyes open for a ridiculously good deal on a mess jacket or an Eton. I don't go formal very often--every couple of years--but wouldn't mind having it ready to go.

I noticed the "dip" in the back in one of your pics. Is that the norm for civilian style mess jackets? I never really noticed it before. It's kind of like a bobbed tail or a vestigial remnant of long tails. I'm not sure if I like that part, but I wouldn't see it so it really wouldn't matter.

I really dig the cuffs though. Much nicer than the US style military ones. I'll probably wind up converting a bargain tailcoat before I find a really good deal on a mess jacket.

It seems a bit unbalanced with three buttons on the right side, but I'm used to seeing them on both sides.

Congrats on the find! I'm sure it will serve you well for many years.
