Hmm, for wig from Fan+Friend they don't seem to have anything that looks like it would work for Jasmine You and they also seem a little skimpy on the 'hair.'
You'll need good full wig that has bangs that reach atleast below your chin. The wig will also have to be quite thick, or you'll have to sew wefts in, due to the massive amount of curls Jasmine has.
I've heard alot of good things from other cosplayers about the fullness and quality of Arda Wigs
Thier wigs were designed with spiking in mind since you need a really full wig for spiking.
