She is still legally a male. She is NOT full time because her legal name makes that impossible. She is a full time crossdresser right now which is what we ALL were before that name change. There is nothing to be gained with going to the hearing crossdressed. Who really cares what she FEELS like? The judge is going to look at the documents then look up at her and see a man who is dressed as a woman. This is reality.
Paula will have fewer options after the name change and certainly after some feminization surgery, but right now she can put on a suit and pass 100% as a man, with the added bonus that all of her documents match her male presentation.
This is a no brainer to me, but then again I tend to be rather pragmatic about these issues. There aren't enough words to convince me to do something I don't want to do, but since Paula is asking (something I wouldn't do) my advice is; Don't make things harder on yourself for no good reason.
Some people here may give you a hard time for it but who gives a damn what somebody who may not even be a real person thinks? You are not far enough into your transition to bother with these ridiculous distinctions. You will not always have the luxury of pretending to be a dude, so do it while you can. This isn't a game, this is life and life is hard enough without stupid imaginary rules.
