/cgl/ - Cosplay & EGL

Looking to cosplay Kahaku from To Your Eternity but I need to buy as many parts of his clothes as possible (due to a physical disability I can't really sew or cut). What are the different parts of his clothes called, for example the red half-skirt thing? Are his pants totally normal white pants or something special?

Alternatively could anyone recommend a good custom cosplay service that won't kill me in shipping to Japan?

I wanna cosplay Kahaku from To Your Eternity, ideally buying as many parts as possible (due to a physical disability I can't really sew or cut stuff). He and his relatives wear this kind of clothing, which I've seen before in other anime but I have no idea what the parts are called so can't even begin to search. What's the red cowl thing for example? What type of pants is he probably wearing?
Could anyone tell me the clothing item names or any characters from other anime that wear close enough clothing I could buy costume parts from their outfits?

Alternatively, I could use suggestions for a shop that does custom cosplays and won't kill me in shipping costs to Japan. Thanks in advance.
