Things to be weary about the Mikasa Ackerman Anime wig: If you have a big head or long/thick hair (I’m graced with both which is horrible for cosplay) you can find putting on the wig by yourself to be a challenge. Straps Tailor-made in your own measurements.This costume can be made for both adults and children.Shippi.. There are adjustable straps in the wig, cosplay characters female but for the most part large heads will have a hard time unless another person is pulling the other side of the wig for you.
