Aaaaa sorry I didn’t answer sooner! Tumblr didn’t tell me I had an ask oops.
The tunic was made out of flannel (aka what sweatshirts are made out of)
I painted the space symbol by hand out of memory with white fabric paint
the hood and skirt are both made out of cotten based polyester
I got all the materials at Jo-Ann Fabrics!
Hope this helped! uwu
