I don't actually suffer from the need to "narrow down". I have four kilts:

1. Modern Douglas (family tartan) 8 yd 16oz hand-sewn tank
2. Modern Douglas 16oz 5 yd casual
3. Black Shadow SWK heavyweight
4. Irish National SWK standard

The only one that I might add is the SWK Green Shadow tartan Heavyweight.

That being said, I have an ever-growing collection of accessories. Hose, sporrans, jackets, hats, pins, etc. That's where I get all my shopping in. I kilt part is easy, but the accessories make the outfit. And depending on where/when I'm wearing the kilt, the accessory package has to be changed, most often drastically.
