If you poke around long enough, you can find Saxon dinner jackets made in all sorts of summerweight fabrics, even including seersucker and madras, especially if you don't mind examples from the 1950s or 60s. Nubby white or cream silk is fairly common once you get past the rental stuff. I was thinking earlier of a tropical wool 3 button navy blazer I have with just a touch of slubbing woven into the fabric- thinking how it would be a great candidate for the Argyll chop if it weren't so handy as a sportcoat. It has 2 vents and even has silver buttons already. Best of all, though, is its weight.

There is a thread's worth of controversy over whether or not midnight blue/ navy blue/ any other blue is sufficiently formal for any given occasion. I vote yes, provided everything else matches the event.

Were I lucky enough to find a white linen jacket, or even a sufficiently constructed white cotton drill one, I would strongly consider it for summer/ tropical kilted evening wear, except that I have never had occasion to attend such an event. Maybe having the outfit would be occasion enough. My dress kilt is on the peg until September or after unless I have a kilted funeral, in which case the linen comes out.

My linen jacket is rusty brown and it goes with anything that isn't red, but I will be the first to admit that it is strictly daywear.

The sad thing is that sometimes tailors and manufacturers lose sight of why we want linen and light colors in the first place. They produce garments that are cool only in appearance. Too much interlining, etc, defeats the purpose.

A gentleman I often copy has a red silk sportcoat he chopped off into an Argyll. He wears it to our local society's (men only) black tie Annual Meeting, which is usually in November, but when we are in front of the ladies, he reverts to a black jacket. I have bought a red blazer with his idea in mind, but then I have my notorious red PC. One CAN have too many kilt jackets.

Every time I wear my cummerbund "slits down" my straight razor falls out.

Oh, and since nobody else has said it out loud, what about Bertie and Cannes? There, it is out at last...
