Sandford, you've no idea how many times I've wanted to quote Dunakin's little book, but resisted! I love the part where he comments on the trends in ladies' skirt lengths (something about no woman having legs worth looking at above the knee . . . )!
I agree to an extent with what he says about the PC, and the same applies to the Montrose doublet as well. I go against his advice and wear a PC because I feel that it bridges the gap between regular black tie and highland wear, and looks at home with the tuxes. That and the fact that it was given to me and I can't justify buying another formal jacket! I'd love to wear one of the other doublets I've seen, but for the occasions that I go formal, I feel more comfortable in a PC.
