I believe both options are fine, but Paulenrique's answer is a perfect match.
Every woman and all the women can mean the same, as well as toda mulher and todas as mulheres.
(Besides the second option - todas as mulheres - can be used to a specific group of women, while the other can't)
If you mean literally and formally, ladies translates to "Damas". If you mean "the ladies", very colloquially, like you would see in a hiphop clip, you can say "mulherada". ;-)
