I have like 25-35 brushes. Minimum you should have like 10-15 brushes of good quality and multi-purpose.How many eyeshadow foundation brushes do u own? How many is average?
i own so many brushes its ridiculous.. from MAC, clinique, some enviromental brand, bare minerals, and other various ones. If i see some brushes i think look like they are soft than i buy them. I dont even use half of them.. but sometimes i switch it up. I also have a bag of different concealers... i have entirely to much makeup. So thats average. Do what you want. buy more brushes just to have a variety.. lol
