There are not many wigs that come in large cap sizes so anyone who has a 58cm or above head circumference really struggles to find a wig to fit. Or if you have a lot of hair underneath your wig cap, this has the same effect.
I can offer a specialist wig alteration service to cut and make the wig cap larger by altering the adjustment sections at the back of the wig (section 5 of image)
If you buy a wig from wigwonders, this service is free, alterations to your own wigs will incur a fee..
