I have a lot of issues with this honestly. I've been dressing totally en femme when I'm at home for almost 4 years now, but still get terrified if some random salesman knocks on my door, and feel compelled to immediately do guy mode, though he's usually gone by that time.
I've only done totally en femme on several Halloweens and did it on TDOV this Spring. No one said anything when I hit the mall on TDOV. Walked all around it, and even bought a sandwich at one of the sit down restaurants.
What I have been doing is just going more and more androgynous, and then pushing it more feminine. When I started out I was scared to even wear men's skinny jeans, now I wear almost all women's clothes and makeup most of the time. Still not real comfortable wearing women's shirts, but that's mainly because most of them make me look pregnant, and I'm not at all comfortable wearing skirts or dresses out, but pants, shorts, and capris I feel fairly comfortable in.
The underlying issue still remains, I know I shouldn't be ashamed of being trans, but since I have parents who engrained in me that I should be, it's hard to shake, especially knowing they aren't alone in that opinion.
