I think the first thing one should understand is that gender identity isn’t by or is about clothing and whether or not appears full on femme or masculine. Gender identity isn’t determined by anatomy.

So whether or not a person dresses in clothing marketed for women doesn’t mean that person identifies as a woman.

For someone who is genderfulid in their gender identity, it’s my understanding that their mental and emotional state has them feeling more feminine or more masculine on any given day. The period can be as short as a few hours to as long as months or years I suppose.

Personally, I don’t fully understand but the best of my limited knowledge that is a watered down version of a genderfluid identity.
