No wonder. But most of the costumes come from Hong Kong, Guangzhou or other parts of China... I believe cloth should be even cheaper there.
I said INDOCHINA.
I doubt with China. One, they're trying to make a shitload of money off of foreigners. Second, while things from China are cheap here in the US, nothing seems cheap in China itself. ;v; I get confused over them pork prices even. So, bulk cloth for like mass-production for export, yeah, cheap. But individuals buying cloth within China? Probably more expensive than in the States.
My mom makes a lot of my clothes, and she used to always hunt down the $1 per yard stuff at Walmart. Albeit, they are cheap and sometimes have poor designs dyed/printed, but my mom always choose decent quality stuff to make durable clothes out of. But, now that I think about it, it's been at least five years since she's even able to find any clearance cloth for like less than 2 dollars. And that's just clearange stuff. My mom stays away from the regular priced stuff, because it's just way too high.
