Headwear?

[imbrius]

With a saxon suit, I wear any number of classically-shaped fedoras (especially for Masonic functions as Past Masters wear hats outdoors by local tradition) colored to match my suits.

For very formal occasions, I wear a custom-made black Tyrolean my father-in-law got for me in Austria.

For casual wear during sunny or rainy conditions, I have a brown Thorpe fedora and dark green tweedy felt wide-brimmed fedora.

I would not consider wearing any of these with a kilt unless it was a sunny day and I'd be spending more than a few minutes outdoors, in which case I would go with one of the wide-brimmed hats for sun protection.
