Kilt braces, or to use the non-British term, suspenders

[pofloyd1]

If I remember right Father Bill mentioned at one time about sewing the buttons to the inner-apron two for the left and two for the right, then sew two to the back, I put the bottons inside like I do with my pants. I did this to some of my kilts and used the button suspenders I use with my pants and shorts. Works for me. Thanks to Father Bill, almost no pulling the kilt up now.

To be honest, I'm not sure where I actually attached them without running upstairs, but yes, they're on the inside, and fairly to the side.
