Help identifying fabric!

[Dicentra]

So I just got someone asking me about making them a Joker Arkham Asylum suit and before I even begin going down that road I want to figure out prices etc...I can't figure that sort of stuff out without knowing what fabric to buy. I know my fair share of fabric types but I just don't know what type this is/would be considered.

Could anyone tell me what this fabric is?

Most suits are made from wool, but don't feel you need to use wool for a costume, because it can be expensive, hot, and most especially, not come in the color you need!  Personally I would start looking in cottons, and then move on to cotton blends.  You probably won't be able to find a fabric exactly like the model, but you might be able to find one with an alternating blue and white stripe which could be overdyed purple to look like the model.

Here's a bunch of striped fabric:  http://www.denverfabrics.com/c/133/Stripe-Fabric

I know this isn't a huge help, but might give you a place to start.  Worst case scenario is you have to custom paint fabric for the costume!
