This is a pretty good question.
In my case, I identify very strongly as feminine. It's a bit of a surprise to me, but that is what I find when I dropped the armor of the male persona. I also identify as a professional, albeit retired. Orientation-wise, I am sexually and romantically attracted to women, and not at all towards men.
Personality-wise, I find that I am more extrovert than the old male persona was by quite a bit. I'm also pretty much 'out', and do not deny my being a transgender person. Oh, I don't wear blue, pink, and white bunting everywhere, but if the subject comes up in friendly conversation, "Why, yes, I am transgender. Now, which show time works better for you? ..." I try to put my best appropriate presentation out when in public. I feel that as a transgender person who may be read as such, I am in some ways reflecting on and representing our community. If I'm going to be clocked, I'd rather be clocked as a classy broad than someone wildly mis-dressed for the occasion.
All these things inform my social gender presentation.
Once I stopped suppressing that core identity, some things about basic movement and posture came very easily and quickly. I don't know if these are intrinsic or stuff I absorbed early in childhood, but it is there and I certainly express it. I have decades of catching up to do regarding the social behaviors and presentation we would normally learn growing up in a gender role matching our true selves, but I do intend to learn these so I can have the best apropriate presentation.
This means that when I am going out walking through our shopping district, I wear what most better-presenting women wear. I do my makeup, and I try to look my appropriate best. when I had to go into the hospital today as a patient, I followed the guidelines. No fragrances, makeup or jewelry, simple loose-fitting clothing I could change quickly, and so on. I made my appearance as neat, clean, and crisp as I could under the guidelines. When I'm going out to do lectures, I'm generally wearing a blazer and either a light turtleneck or coordinating light scarf on my neck, flared slacks, and reasonable shoes for spending a couple hours standing and talking.
I am working hard on my voice, discreetly checking pitch (phone app and/or a little vocal trick, "Ummm/UhHuh" before speaking to set pitch), and always trying to talk at pitch and with good prosody. Everyone gets 'the voice', even folks who knew me before I came out or strictly within the trans community. I do not want to form a bad habit of 'slipping' when I think I can get away with it.
I try to stay fit, and watch my weight and figure. I'll live longer and/or better this way.
I feel that I am doing much of this for myself, since matching society's concept of gender presentation matches my goal of getting my presentation fully in line with my identity. This is certainly related to my age and old concepts I was raised with, but that is common among many folks near my age.
Who knows, someday I might get past Weird Old Lady and become the classy older woman other ladies of my age and orientation seek out. A gal's gotta have dreams, right? 😼
