I think the above works the opposite way too: in that if you do normie light average makeup, you probably really are busier and it’s a typical day. But if you’re either not wearing makeup or wearing a lot, it’s more likely some special occasion or you’re more open to random things entering your life and it unconsciously shows too or something like that.

It might also have something to do with confidence that gets projected, or is implied with either none or a lot of makeup
