Yes, I am really into porcelain dolss with fab hair and clothes, but I cannot make those as I have no kiln and no place for one! So I am doing newborning, but my heart is with the porcelains!
They have a nice selection of the more Victorian type of wigs, including one called Charmaine 123 that looks like the one you like. Hope I am not repeating what you already know!
You can use the search feature for "wigs" and I had posted a few places to get nice wigs, including Monique's as Bonnie said above. Monique Globaldolls Kemperdolls Wee3 Secrist and Apple Valley (Secrist's sister company) also has wigs but not the kind you are looking for in this particular case.
