In the '60s, they had these crazy brocade dinner jackets, which are nice.
I have a length of scarlet cashmere i wouldnt mind making into a SB 3 button party jacket. One of these days when i get bored with what I have.
Yes, i'm a fan too of the madras and tartan jackets. A Harris had some nice looking cashmere coats for sale recently. Unfortunately, the madras and tartan wouldn't suit my body type, so i'll never own one.
I have several. I wore them a lot more in college than I have recently. I should get back into that.
