Hey Barbie,
The others were right about the smile. It raises your cheek bones and makes your face look a little wider in the middle; more oval than rectangular, (a more masculine configuration.) Two suggestions: Although I love your long, straight black hair, if many of the girls in your country curl or perm their hair, (I understand you don't want to stand out), you could add just a little wave right about at the cheekbones, with the lower portion angling back in. A curling iron will work fine on real hair; if you're wearing a synthetic wig, you'll need to use a little styling product designed for wigs and just a few of those big rollers and leave them in for a little while--you can't use hot rollers on synthetics. That will do the same thing as your smile does in making your face look softer and rounder and less long and angular. There are also make-up tricks that will do the same thing, but I'm not an expert and would have trouble explaining them. But there are books available and sites online that give make-up tips for different shape faces. But the most important thing is to remember the comments of everyone who replied and that is that you are really lovely. Tall, pretty girls catch people's eyes and turn men's heads; it doesn't mean that they "read" you--they were probably just enjoying the view!
What's really great is that you're getting out now while you're still young. I waited a long time, until just four years ago, until I felt brave enough to go out as a woman. It was, and is, truly wonderful; I just wish I'd started earlier. Good luck finding ways to dress as the beautiful woman you are more often, but most of all, enjoy every moment!
Lotsa' love, Vicki
