I own three.

1 Black economy
1 Irish National Standard
1 Black Shadow tartan Heav tweight

Why did I but them?

Price and service.

Where do I wear them.

I wear the Irish National and the black Heavyweight to some highland games, and around town on occasions. The black economy, I wear around my property much of the time, doing about anything from bush hogging the lower field to watching TV. I alternate it with a couple of Sportkilts.
