Hmmm..Edmond. Its been a few years but try McCalls on Broadway...down town area.
I really recommend S.J.Haggard & Co...6436 Avondale....over in Nichols Hills Plaza.
Both stores will make you a suit or tailor it using their brands of material or suit company.
Sorry,no-one in the state that I know of just makes you a suit from material you select from their stock...like Hong Kong or London. I may be wrong....but none that I know of.
I dont know anyone around here who makes suits from scratch. But then next time I wear a suit - the back will be cut open so they can get it on me easier.
I'm not sure if you're looking for a tailor to make a suit or someone to alter a suit. If it's the latter, there is a woman who runs a little alteration shop in Edmond in the shopping center at the SE corner 15th and Broadway--kind of back around behind Ace Hardware. Her name is Kelly and she does wonderful work. She does all our alteration work.
