I have made one of these from DPM, a three colour traditional type of disrupted pattern, but not military here in the UK, where military uniform camo is either two or four colours.

I wear it with a 'real' 1958 pattern belt with brass fittings, and one of several khaki tees or a dark cream shirt.

When constructing one of my kilts I usually sew everything by hand, but in order to get a slightly different waist I used the sewing machine to sew each individual fold HORIZONTALLY about two inches down from the upper edge, for about two inches along the pleat. This was to set the fold of the pleat at that point, so I could then sew the pleats in place at that level and then slightly flare the top - so making the narrowest point of the kilt within it, rather than at the top edge.
