Seeing as it's getting a bit cold for my SWK Heavyweight (and I cannot even remotely afford a tank in the forseeable future), I was considering the option of tartan trousers. That said, I'm at a loss as to where I might find such a beast. Furthermore, I do carry something of a paunch, resulting in a 45.5-inch waist (for reference, I have a 48-inch chest, and 20-inch shoulders)... this probably rules out the usual slim-fitted fishtail trews. I've seen "Argyll trews", which seem to be trousers with a taller waistband and loops for a kilt belt, and tartan trousers, which are simply standard trousers in a tartan fabric. The latter two also seem to cost less than the former from most vendors.

Thus, I have two questions to pose for the Rabble:

1. Where might I source a pair of tartan trousers or "Argyll trews" for a reasonable price?
2. Which cut should I get to avoid looking like an eejit?

Thanks,
Livonian
