You are missing something and that's realizing that clothes can be a big part of LOOKING feminine, but are in no way the determining factor of BEING feminine. While wearing dresses is quite a feminine visual cue, it doesn't make you less a woman if youd prefer not to wear them. Sometimes a casual, laidback style and a little makeup is all you need. Just don't feel less feminine because you see dresses aplenty here.
I think some ladies feel the need to go all out, possibly to make up for lost time, and that's alright! Our common link here is transition, but we are all individuals with different styles, interests, and lives.
