Regarding flicky eyeliner, I have dug out my copy of Pretty Honest and here is what she wrote on the very same subject
"Those iconic feline flicks of liquid eyeliner, beloved by Bardot, Monroe, Fonteyn and so many other glamorous women, will never go out of style. I wore flicky 60s liner for years and while it will always be a look I love, I've parked it momentarily until its huge moment in fashion passes. Because the point for me is that flicks are special- they require effort, patience, maintenance, occasion and a half-decent outfit. I don't want to wear them when everyone's at it. There are still times, though, where only a flick will do and I'm terribly grateful for my ability to draw then"
So, they will never go out of style but you're waiting until their "huge moment in fashion passes". Which is it?
