Dear Josephine,
Thanks for contacting Top China Travel!
I am sorry to tell you that we specialise in China inbound tour, so we have no idea about the various prices of cheongsam dressess and the different qualities of material used to make them. So you should go to other places to look for the information that you want. Sorry for not being able to help you.
Any further request or question, please feel free to contact with us.
