Certainly, "some" women have body dissatisfaction, low self-esteem, depression and consequently feel that by wearing lower cut tops, or tight jeans or showing off their legs may get them more attention and that's what it is, attention seeking but what for?
Some to attract the male species for believe it or not, relationships as that's all they know, they see the Models, read the magazines, find the girls attractive, hear their friends of the male species comment on their butts, boobs and feel that if they looked like that, they would get the attention and consequently a man.
Some for the purpose of money, be it that they are a waitress and want more tips, be it that they are a Model and want a rich guy.
Then there are confident women who like who they are, inside and out and dress for themselves, not caring if some guy is sexualizing her and have no intentions of wanting anything from the male species.
There is sexuality / sensuality - of one self with total respect. Yet a male may perceive her as sexualizing themselves for "them".
There is also sexuality - to gain attention, but inadequate self-respect can be only one portion not the be all and end all of the reason. A person can feel inadequate about their body but that does not mean they don't respect themselves.
As for wearing lipstick and therefore sexualizing I totally disagree. I dress for me, wear make-up for me, there is nothing at all wrong with wanting to look nice, attractive for me, if others find that also the case or want to fantasize that's their problem. After all if there was no sexual attraction there would be no relationships, babies. The problem is, a lot of men sexualize women. She wears jeans and has a nice butt. She merely put on a pair of jeans. Yet, this attracts many a stare from a man because he likes nice butts. Doesn't mean she was asking for sex or trying to get attention.
It's a tricky individual situation.
