I have a few, but the best one I bought from a supplier who advertises on this site, En Femme, and it is a Henry Margu lace front. It is a synthetic, but has a realistic look, and I wear it out often. When I used to be able to go out to various CD events and I’ve told someone it’s a wig, they’ve said they would never have known.
The colour and style is important as well so you get something that works with your natural face shape and colour. I still have a full head of hair, so I use a band, but my hair is quite short, and I now keep it that way so me wig fits well without issues.
The cost, I’m not sure but I think it was in the $150. range. Not cheap, but not really expensive, but my standards anyway.
The vast majority of the pictures here of me are with that wig on, if you care to look.
