For me a lot of things just popped up when I stopped hiding them, others I had to work on and I'm still working on some of them.
Interestingly enough my Mom actually prepared me well because she was very adamant about proper etiquette having attended a finishing school for girls, I don't think she realized that much of it was mostly targeted towards ladies so she raised me to walk, eat and socialize like a girl without realizing it

Fashion is a non issue, always had an eye for fashion, been helping my girlfriend with her wardrobe since we met and went shopping with my girlfriends when I was younger.
Make-up took a couple of weeks on Youtube and some practise, it's all about details and realizing which things to emphasize and hide, some technique but that's just practise and a steady hand.
Movement and walk came very naturally, just a bit of deprogramming and I started gliding.
Voice is the hardest, people used to tell me my voice had a feminine quality but getting everything in line takes a lot of practise and work, there are some tricks that can be used but I don't want to sound nasal or like I have a lisp.
