You didn't say when or where you are going to be married. It may well be that you can rent kilts and adapt jackets, depending on time, budget, etc. If you devote a few hours to searching threads here, you may find alternative jacket suggestions, either to buy or rent. Of course, shirts and ties, while convenient to get with the rental, can be bought anywhere, including non-kilt vendors, and hose should not be a problem.

Congratulations and welcome
