Why do sexy costumes exist for females?

Some women (most) like looking good.  They like it when a man genuinely compliments them on how good they look, how hot, how sexy.

However, they do not like derogatory remarks. 

Some women take it too far.  and Some people refuse to watch their mouths, especially when drunk. 

Some men have been taught that if a woman dresses sexy she wants sex.  

NOT TRUE Women want to dance. They want attention, but only a little bit. And often, they want their girlfriends to tell them they look way better than normal.

Sexy costumes exist because the majority of people like them, either to wear or to watch others.

because us guys love sexy kittys nurses cops etc

Honestly because it’s enough seeing women wear them thinking they look good we don’t need the men too

Women are funny and switch emotions of who gets to look at them or not while they are out in public and how they feel at those moments but anyway .....

Companies have supply and demand if women are wearing and buying these sexy costumes and men / women are benefitting from it then why stop making product of profit if it makes them money .

Maybe that's the attention that they are after.

Females want to see other females, maybe comparing themselves. 

Female tastes reign because they have style leadership. 

Sexy costumes only bother females, so only males are affected.
