>>9554938So to my understanding, Calle has a 10.5cm head, meaning she has a 4 inch wig size. This is already a difficult size to shop for, but that's compounded by the fact she has a "strangely shaped head" which, rip friend ive been there. Currently deciding how to make a wig for a Gulliversmall doll and damn.
Your best bet is to buy PukiPuki and Lati White sized wigs, and ideally long hair styles as that will help conceal any oddness in the shape of the wigcap. Honestly that's a hard size to shop for, and synthetic fibres tend to look really bulky on that scale, so I'd recommend natural fibres or acrylic yarn.
There ARE people who do commissions for odd wigs, but you'd likely need to send the doll head to them.
Have you considered making one yourself? They aren't so hard to make and you can get acrylic yarn pretty cheap from a craft store. Honestly you'll be able to get the best fit by making one yourself/having a custom made one.
