I comepletely identify as a feminist and yet wear make-up every day (not much most of the time, but some) and heels when I go out.
I'm 5'9" so definitely do not need to wear heels. As for make-up, I completely see that the only reason I want to wear it, or feel better about myself for wearing it is that I have been conditioned to think that.
To deny that is sticking your head in the sand.
I'm in my late 30s so not quite at the need for improvement stage - but why do women in their 40s, say, feel the need for a bit of concealer, touche éclat, tinted moisturiser, high beam - whatever - when men don't? Why do women's complexions suddenly need a whole lot more concealment and improvement as they age, when men's don't? 
So, I'm a flawed feminist, definitely. I do something which, when you look at the bigger picture isn't great for society/women, but I'm just not prepared to go the extra mile myself and forgo it, since looking good is important to me.
But - I see it for what it is - something I've been conditioned to do and feel that I do for myself, just as everyone on here seems in such a rush to protest ('I do it for meeeeee, not for anyone else, and certainly not for a man!!'), but I also 100% acknowledge that things I need to do to feel better about myself (lengthening and defining my eyelashes, say
) are not things my husband does to feel better about himself. Why not?
Wear make-up if you want to - I certainly do - it's a free world. But to refuse to join the dots and at least see what it leads onto, bigger picture-wise, is just ignoring what's right in front of you, IMO.
