Hi PandaCutie,

If you don't feel save coming out than you don't have to. You are still valid and a they. I come out in small steps. First my bf, then friends, then university etc. Mostly I start having a general conversation about the topic with those people and decide along the way if they seem friendly and safe - or not.

However, I know how hard it is to be misgendered all the time and to act like someone you're not. For the pronouns I have no solutions, for your presentation; Depending on your environment (job with dress code vs university), I can recommend small things like trousers from the men section (I wear boy's trousers, they are smaller on the waist), big shirts, short hair, boxershorts ..
These are all things people usually don't mind women to wear (you might get a few comments but my overall experience is; noone cares). But for me it was a step away from beeing overly female (and I was twice percieved as a guy. Which is also not true but it felt good for once not be seen as a girl)

Do what makes you comftable (You don't have to cut your hair to be you for example).
Surround yourself with friends you can trust and were you are free to be you - small islands where you are not misgendered.

If you prefere a more direct confrontation with the bigots around you: Pronoun-button, shirts, flyer, ...

I wish you strenght and good luck on your way
