How difficult it is to obtain a good quality costume which is not commonly found nowadays?
Kamituro was the first I saw kigging and he captivated me ever since, especially his Saki cosplay. Now this anime is more than a decade old now and barely any shops have even the option to search for its costumes.

My question is: is it possible to commission something like this from a costume maker in hopes of being top notch ( money is not a concern obviously )? And if yes is there any western costume maker who you think could handle it/trustworthy?
