Fishtail back on kilt with button braces?

[Kriegbert]

I do see your point. I suppose the distribution of weight would be extended evenly along the base of the fishtail, more so than being distributed across four buttons on the inside back of one kilt.

Kind of like overalls minus the flap in the front.

The biggest two advantages with braces seem to be: since they hang from the shoulder, the waistband can be loose, which is particularly useful if you have a large meal, and secondly, always reverts to the original position regardless of whatever acrobatics you pull off.
