I am very pale so I can use white flour as loose face powder! Any kind of white flour will do. I keep mine in an empty Bobbi Brown face powder sifter jar and apply with a brush. It works wonderfully and you can pick it up at the grocery store. I think it's perfectly ok to use flour as face powder. They did in ancient times, and it's basic and it works. Imagine having an inexpensive large bag of face powder that won't be discontinued. I really love it. No, I'm not Goth, just fair/light and it works for me! I've used Nars, Chanel, Bobbi Brown, you- name-it expensive powders (got many pretty empty sifter jars!) and flour works just as well. Sometimes I even grind it finer in a coffee grinder before jarring it, but I don't really think you have to, there's probably not much of a difference. It's already fine powder. As the saying goes, if you think it's cool, it's cool.
I think it's cool.
