Joshua, I had two kilt jackets and waistcoats made by a tailor in Bali and the only knowledge that he had of how they should be cut, was photos that I provided him of HRH Prince Charles. As long as you provide your tailor with photos of the jackets/waistcoats you want (fom every angle you can) and emphase the need for the cutaway, I would say go ahead. The jackets I had made were not argylls. They were classic cut as I think you are intending to get and I think they look great as a kilt Jacket.

Kyle (creagdhubh) has numerous photos of his on the forum
