I would like to pick up sites that cosplay can purchase through mail order.
"The Ichiban cosplay"
Factory direct delivery, cheap and high quality anime cosplay mail order shop "No. 1 cosplay". Cosplay costume of animation and game, costume, cosplay boots / shoes, cosplay wigs, props, and so on. The product seems to have taken the real thing as it is. Http://www.ichibancosplay.com/
"KOSEYA"
I think that it is easy to purchase because there is also an English site here.
