You could also read other fantasy books set in the same time, to see how other authors dealt with it. However, I would recommend caution, because if you get too in depth with description, it can really slow the story down. It's hard to find a good balance!
It is very very hard to go too much in depth with description. It is easy to do bad description, though. Watership Down is one of my absolute favorite books: amazingly compelling, exciting, powerful, vivid, and all around really good. It will spend whole pages of simply description with absolutely nothing actually happening. But it is masterfully done and irresistible (unless you hate books

). The same thing with any other really good writer.
The thing is not about rules of how to do good writing: it is about how to write good. Make sense?
Sorry, got on my soap-box there. (To borrow the colloquialism.)
I would suggest making up your own clothes and then introducing them into the descriptions and story carefully so that your readers do not get confused. That is what I do a lot.
