I need a cool cloak/belt/shoes to match this gear

Hello, 

I am a frost mage and I recently got this transmog gear:

But I would like a cloak that matches the gear. Maybe red with some cool black design? I would like it to be the very long type of cloak (not the medium or short capes)
I also need a belt and shoes for this. Also a staff.

Thanks,
Arcanen

(I picked that gear because it looked cool and I wanted a hood)
