I like trews and certainly regard them to be as traditional as the kilt. I also think that the tartan egg cup phenomena is by no means exclusive to trews. It can equally apply to kilts as well! (Especially with a low hanging sporran to accentuate the look! )

I offer trews for sale but never receive any orders for them or even inquiries. A shame really, because one could put together a formal trews outfit for much cheaper than a kilted one. (Less accessories to buy.)
