Narnia and LOTR clothing influence?

Okay, so I'm trying to find out what time period the Narnia and Lord of the Rings clothing came from. What did they? Were they influenced by the 1400's or what? I need to know!! Or even just the fantasy genre that has the same clothing style as these movies/books? Where can I find names for these clothing styles, when were these worn, and possibly an image gallery of this clothing style? Please help !!
