How do we know this is a female? Both genders look exactly the like, last time people had this type of a debate it went to ambiguous even with the artist saying it was a guy?

There's breasts.
So TWYS -> female.

I assumed it was the floof underneath the clothing, closer look, they are indeed breasts, explains why it is tagged female indeed.
