I used to just go back and forth a bizillion times until it went on 🤣 Eyeliners I like are mainly the victoria beckham ones, estée lauder and Patrick ta.
I actually don't wear such a prominent eyeliner below that much anymore, I do still do a thick line above. But below I tend to do a third of my eye with eyeliner on the outer side, just under the waterline, then blend it out and in with a thin angled brush to create a softer look. Sometimes I just use powder if I want it to be even softer.
