Hi,
I will agree that depends on every person because as far as I have found out, feminity is understood differently for every one of us.
In my case, it is taking me my time. Following on the list provided by Danielle:
For the MTF:
*longer hair in female styles.... braids, ponytails, buns, etc. - Done and part of my life and very happy. Now moving to longer hair under shoulders and reaching my chest
*fingernails and toenails polished - toenails done every other month and very happy with it. Fingernails every now and then.
*hair removal as needed and where needed. - Oh yes...getting rid of it. Only left from neck upwards and really satisfying.
*jewelry, necklaces, rings, bracelets, earrings, wrist watches, etc. - Not so much.
*tasteful and "not over the top" makeup, lipstick, etc. - Not so much
*female gendered clothing and colors.... which can include androgynous clothing. - Sometimes, more neutral.
*female oriented footwear - Not doing it
*dieting and exercising to allow wearing tighter form fitting clothing. _ Yep and loving it.
*walking, moving, eating and talking in female ways. - Trying my best and learning by the day. I sometimes laugh at myself when doing the catwalk.
*voice training if needed. - On my bucket list, but too many tips and tricks and tutorials and too little time. Looking for the moment to go to a professional to get proper training...but not in a huryy.
So, as you can see, in my case I am going at my own pace, changing those areas that make me feel happy.
I will also add that I am researching different doctors to have the studies done to go under different surgeries (adams apple, FFS for the moment), but first I need to know if the prices, the timeframes and the time to be in hospital, so I can plan.
But I am not putting any pressure on my transition, I am moving forward as I feel comfortable, which would be my advice. Go at your own pace and checking your own "happy milestones".
Love.
Anne
