My first step was perfume. It really reduces my dysphoria too. Then start donating your boy clothes. I have almost zero boy clothes now. I have a nice suit that is about it. Like you I also wear light makeup. I wear tinted moisturizer, eyeliner, eyeshadow, blush and lipstick, no mascara, don't need it. Another step is to get your ears pierced. When you've done that subsequent steps of getting more studs, then coordinating your studs to your outfit. Then of course graduating to dangly earrings. I haven't done that yet. Of course don't forget about weight loss and electrolysis. Both of these are ongoing for me. Another is no more wallets, get a purse. Oh, one I did early on was getting androgynous shoes. Then I donated all my boy shoes. I did a major step of restoring my hairline just a month ago. I really don't want to wear a wig, so this is impt for me. Then of course are the various coming outs and name changes. Whew, enough yet?
Good luck! I hope these give you ideas. I'll be watching the thread too, as I'm always looking for ways to push the envelope slowly during my transition.
