Christine,
Congratulations! You took a very big step and I'm proud of you. It takes so much courage to tell anyone and especially our families. You have reached a milestone that so many have not. Don't fall into the trap, questioning why you didn't do it earlier and continue moving forward.
I would suggest you talk to your mother in more detail about what's going on with you. I can't imagine much more was said when you told her initially since so many emotions were involved. Try to get a better understanding of her feelings and allow her to do the same with you. If things went as well as they did, I would imagine, wearing your clothes around her will not be a major issue. Either way, talk to her and tell her what it is you want, but be compassionate and caring for her feelings as well. For all you know, she may assist you and teach you like a mother would a daughter.
