Not sure where in the World you live, or how much money you have to spend.

My suggestion is that since you're a piper spend top dollar that you can afford with a quality kiltmaker and other vendors. Avoid middle men - work direct wherever you can.

Consider Lochcarron made-to-measure Argyle if you don't fit off-the-rack sizes well. Time to order and receive a made-to-measure by then if you order soon.

May also be worth the effort to put your own package together from the best vendors if you're able to afford that.

You sound rightfully proud. Show it in your turnout.

The sharper you look the more likely you'll be hired for more gigs and the more money you'll have to afford a top-of-the-line turnout.
