Hello guys

I'm in the planning stages of my next project, a tartan waistcoat to match my kilt. After that I plan on making making matching trousers and jacket so that I can either be suited or kilted. Something like Alan Cumming's outfit

I already have a grey Araca tweed jacket and waistcoat, but I've noticed the waistcoat is quite short. Am I right in thinking kilt waistcoats are made shorter so that they don't interfere with the sporran?

So I've tried it on with normal suit trousers so see what its like, but there's quite a gap between the top of the trousers and the bottom of the waistcoat.

So either I make:

1: trousers with a extra high waist line, (making me look like Simon Cowell if I don't have the waistcoat on)

2: or I make two waistcoats, one for a suit, and one for a kilt.

or is there a 3rd option? maybe a waistcoat somewhere in between the 2?

What do you recon? Has anyone had this problem before
