Angela,
I can understand you being nervous but don't fall into the trap of trying too hard , by that I mean acting too femme , for a short time it's OK but sustaining it day after day is impossible . Let them get use to you and gradually you'll find they will accept you no matter what you look like or sound like .
Dressing every day is tricky , you will soon establish your identity and find you can be freer to wear a wider choice of clothes . I held back for a while with wearing a ( denim ) skirt for my painting class , I soon discovered no one noticed . Build your confidence gradually and you'll soon wonder what all the fuss was about , I would suggest you don't do the change from female to male too often if at all , you will find they are confused and will struggle more to accept you .
