Yes

Why do women wear low-cut dresses if not to attract male attention (in the majority of cases)?

Because they think it looks good or is comfortable or is fashionable or they didn't have anything clean or their sister bought it for them and they are seeing them for lunch.

Have you heard of the Bechdel Test[1]? It's a simple way of seeing gender bias in a movie: It has to have at least two women in it, Who talk to each other, About something other than a man.

By thinking the way a woman dresses is about men your comment shows the same bias.

Turn it around: why do men buy Ferraris if not attract female attention?
