Don't know if this goes here, if not please move.
Basically I need a good black wig to wear for Okabe from Steins;Gate and Araragi Koyomi from Bakemonogatari, but I know nothing about wigs. Would I be able to get a wig that would work for both of their hair lengths?
Here's pictures for reference:
Also how does one change their eyebrows to match?
What's a good place to buy a costume from, since I have absolutely no sewing skills.
Thank you very much in advance for the help.
