Both the photos make me itch to get the shirts a bit neater and the kilt higher - though the one on the webite looks rather short. It keeps making me think 'lampshade' every time I look at it.

To me, having a shirt bloused over a low slung kilt looks untidy and it isn't at all flattering.

It could be that rather than shortening, Scratchy's kilt wants tightening so it sits high enough to cover more shirt and show that weight loss.

If it was a solid colour kilt then perhaps shortening would be the thing, but it is tartan and so it has a history - it should be worn in keeping with its inheritance.
