I don't remember the shop, but I was surprised when I typed in a random provisional "Thranduil" search into Ebay just to see what I'd get... and it had the brooch. Yay! The material for the robe is... obviously with a gold-pattern weaved into it.. some kind of viscose? Maybe? I found it in a wholesale shop here in Germany It's shiny but not obviously polyester. Quite nice, not a cheap looking fabric. Sorry, I don't know much about fabrics.
Thanks Really very nice costume Few weeks ago I bought two rings of Elrond from the Hobbit movie and they're great Now I ordered the brooch of Gandalf and Arwen Evenstar inspired ring So I'm looking forward Well thank you
