Presentation is just as important to passing as "how you look". By presentation I mean clothes, accessories, jewellery and anything that contributes to the sense of you as a woman (voice, posture, body language, personality, walk, etc). Now this doesn't mean you have to go all out fem - pink dresses, swishy handbags, a ton of makeup, hoop earrings, an exaggerated sashay - but small touches help. I remember that one thing I really wanted was to be able to pass when wearing jeans. When I first tried to transition the 1990s I "failed" at that every time, much to my frustration. What I wasn't really taking into consideration was that I was still wearing guy's jeans, and nothing about my appearance or hair or presentation said female. Maybe had I been a foot shorter it would have worked but if you're working against a particularly "cliche" male physical feature then some extra work is going to be needed. I watched what other women did with their appearance and learned from that. Even when they were dressing in more traditionally male clothing there were still plenty of feminine pointers in their presentation. These days I can pass easily in jeans due to small touches that say female.
