I'm lucky enough that none of my friends judge the amount of makeup I buy (and really, I've curbed the habit).
But because most of my things get sent to my parents house, and I pick it up from there because I travel a lot.
And my mom will occasionally be like ... "really? is it more makeup?"
Me: "Yes, yes it is."
Mom: "Don't you have enough?"
Me: "What is enough?"
Seriously, haha, I won't judge anyone for buying too much makeup unless they're spending money they need for something else on makeup. If you're within your budget, you might as well buy what you enjoy!
Makeup is a hobby. A really expensive hobby. People don't get shade for buying expensive paints if they like painting as a hobby, right?
