Geoffrey Tailor & Kilt Maker is located on the Royal Mile / High Street in Edinburgh and has been in the kilt-making business for a few generations. They are more on the "bespoke" kilt end of pricing and quality, but you will not be disappointed.

I have one kilt made by them in 1989 that continues to wear beautifully, and visited the shop in June 2024 and purchased an Argyll jacket & waistcoat they measured and sent to me a month later.
