/cgl/ - Cosplay & EGL

want to start piecing together a cosplay of Yennefer from Witcher (the third one is what I'm focussing on), and I'm not sure which wig is best - in-game her hair looks to be in large, fairly loose waves, but most of the promotional art/renders show some pretty tight waves.
I'm thinking it's either something like Arda's Vivien or Glinda, but am really unsure which is more accurate - the former seems too straight and the latter has really large curls. anyone done this before? what wig did you use? what wig should I go for? pic very related, sorry for the shitty resizes
