I am in Japan, what style clothing are you looking for?
My wife is a dressmaker and seamstress, BTW I am American. We often get people wanting to give us their Kimonos which cost them at least $1000 but the Japanese do not sell their used clothing. My wife makes purses and other things from the Kimonos and we have many of them and can supply them in small quantities. The shipping cost is the draw back.
Most people buy the cheap things from China which are cheap imitations. I wanted to sell them but I do not know how to sell women's clothing.
