It's an interesting question. They're both technically women.
However, what is a "real" woman to you? By real I mean someone that you can see being a lasting girlfriend, potential wife, someone you'd be proud to show to your friends & family.
Option A
Someone who dresses revealingly, sleeps with just anyone who shows them a bit of attention; who usually has little to no self-respect or esteem and that's why behave as do
Option B
Someone who doesn't dress revealingly, who doesn't sleep with just anyone who shows them a bit of attention; who usually has self-respect or esteem hence behaves differently
