DO NOT GO TO ISOLATED PLACES. Sorry for shouting, you are in danger in isolated places. All woman are.
OK, are there any Gay friendly bars, clubs where you live? They are usually safe, as they tend to be tolerant. Is there a TG club in your area, check on the internet, they are totally safe and you will meet girls who have transitioned and are willing to help. Are there other GID people in your area? Ask on Susan's, it's easier with a friend.
If none of the above go shopping. Go to a mall and shop for clothes, girls do it all the time without buying anything just looking. If you do so don't overdress or over makeup. Look around at what woman your age are wearing in such places and copy them. Shops are usually no problem at all. They want your money. Full stop. I have been outed once at one store, she was fired. Be respectful, ask for the change rooms if you want to try something on.
Try and relax and be confident.

I know how easy that was the first time

. If you have a relative, or friend to go with it helps, the first time.
The other really good places for first timers are the movies, museums, art gallery's. These are places were people take no notice of each other. When walking around never look for eye contact. Woman don't in general, unless they want to flirt with a guy, and it is probably too early for that. Ignore comments, if there are any. You have as much right as any one else to be out and about. If you go out at night alone, tell a friend and call them when you get back home (another reason to have female friends if you can).
Sorry if I have frightened you. But go and do it. You will be surprised how easy it has and how much fun it is and totally life changing. Once out the first time, there is no way of putting the girl back in the hiding place. And more you do it, the less people notice. I did my supermarket shopping yesterday in shorts, a T, beaut thongy/ shoes showing my polished toes. Make up ( I need a little to hide defects), the check out girls chatted and I chatted back, the deli boys and girls chatted and we had a few jokes. Everything was fine.
One thing I have noticed is the friendly you are the more acceptance you get. I think it is a people thing. If you are a nice person to be with you are remembered as a nice person to be around. The guy who pushed my trolley to the car I had been chatting the previous week about going to the movies with his girl and I asked how it went, I had asked him the previous Sat what was he doing that night (No it was not a pick up line), so we had a talk about the movie and how expensive pop-corn is, and best place for coffee after etc. Final words, see you next week Cindy.
They know I'm "TG" hate that expression. My voice gives me away immediately, I sound as feminine as a jack-hammer. But they also know I'm a normal human, and they treat me as one, and I think I get a bit of special treatment and support.
So Veronica. After all that. Go and enjoy and be safe.
And no my darling, girls who are 24/7 had whatever and look whatever at Susan's have no problems with helping people who aren't. I think the wrath of Susan would fall quickly on any Mod who didn't help out; and the wrath of Mods will fall on any members who were not supportive.
Take Care and let me know how it goes.
If you need more advice I'm sure other girls will be posting
