Kilt Belt (question)

[Sir Didymous]

Maybe I should just go with a great kilt...the whole 9 yards. Then, I could gain or lose waist and I'd still have enough to work with.

If you are willing to go that rout, you could try a philabeg. The early ones were gathered/pleated like the great kilt, but it was basically only the bottom half with just a bit over the top of the belt to provide security. However, that might seem a bit odd with modern clothing. Unless you're like me and wear a mix of historical an modern.
