ETA: Quote fell off. You asked why we wear makeup, @Hadmysay (or @GreenFriedTomato, can't remember.)
I was going to say this is a very basic level of consciousness-raising to be attempting on FWR. But the general timbre of half the replies suggests not! Anyway:
I don't normally wear makeup. I do, though, really enjoy makeup as what you might call a creative pursuit. I love to see young women with fabulously applied makeup - and young men, though that all died out when they started thinking it turned them into women. Pity.
When I wear makeup, it's either because I just felt like doing it or when I'm entering a social situation in which face paint is coded as 'making the effort' - so, as a courtesy.
It's never to attract men, though makeup does make people look more attractive. It gives the appearance of smoother, healthier skin and highlights the features. People of both sexes have used cosmetics for this purpose since prehistory. They've also used makeup to convey tribal affiliations, social positioning and beliefs - and still do.
Fashion/style is a vast, complex topic that fascinates me. It can be a personally individual choice made without regard to society, but rarely is. Of course there's a feminist conversation to be had, as there is about every aspect of social behaviour, but it's nowhere near a simple dichotomy.
Also: bikinis? Meh. Some people are more devoted to an all-over tan than others, and it is true that sun on bare skin feels good.
The comment about men being 'empowered' to walk around with their buttocks on show made me laugh. You should come and check out the guys across the road from me, always fixing their cars with their jeans riding down 😂 Now, that is empowerment! They're free to let their arses shine out, never giving it a moment's thought.
