How to size a sportskilt

[Galician]

Mine usually end up somewhere between my pants waist and kilt waist.
And if your waist measurement is right at the line between sizes, I'd recommend going with the smaller size. I went with the larger size on my first one, and while it was wearable, it was slightly too large.
I ended up giving it to my brother who is also slightly too large so things worked out well.

I might have to disagree. My sizing was on the line between two sizes (even listed for both). I went for the smaller size. I had ordered the works, however, and while I could probably have worn the kilt, the buckles didn't reach.

I wound up selling it unworn and getting the next size up.

P.S. Cephas, mine was in the Clergy tartan, like what you appear to wearing in your pic.
