Does anyone here on tumblr do Persian or Northern African garb and knows some good places for buying some nice period brocades? I’ve been looking everywhere and I’ve had no luck. 

This isn’t a commercial site, but it’s a nice collection of pictures of period fabrics that you could use to compare modern brocades to:

The Met has a collection too:

Spoonflower looks to have some designs that could work:

Good luck!
