Siylon

Siylon is a material used for some fancier clothes on Ellienias. In a nutshell, the name is a literal combination of "nylon" and "silk", because it has properties of both. It's made to be durable and a bit waterproof (like nylon), yet it's also really soft and rather shiny (like silk). It can be dyed to any color you could dye anything else clothing related.   It's not really cheap to make, though, so the material and anything made with it can be rather expensive. It's usually used in jackets and dresses, but it's also been used in some designer-y type clothes and items.
