Which caused idle pondering here...what is it about Burberry tartan, where it has become globally prolific and SUCH a haute fashion item on handbags, wallets, umbrellas, ladies' skirts, dog collars and coats, shirts, scarves, lining for trenchcoats...?

Yet these eyes do not remember ever seeing a man's kilt or trews in Burberry tartan. Curious?

Thoughts and shared observations are welcome.
