I've had a few people ask me where I found the wig I'm wearing a few posts down.
It's the Alonge style by Lacy, in the "discount" version.
Amazingly, the texture of this version is much better for an accurate late 18th century wig, and doesn't look so shiny like most synthetic wigs do.
Here's the link:
Mine is in the Blonde shade, but it comes in many other natural colors.
Not sure if the wig in their photo is the same quality, but it is shown un-brushed.
