Would things be any different if women designed women's underwear?

On another note, underwear advertisement is exceedingly sexualised, and I wonder how and whether women are motivated by this advertising to buy underwear. I suspect if they are it's because it tells them you have to look like this to be attractive to your man or something like that.
