My first few forays out were dressed similarly. Neck up male, below that, female (including forms). Once I even had makeup on with no wig, but still called by others as male.
It wasn't until I added a nice wig that I truly started getting identified as female. Even when someone near me could clearly see I was a guy dressed as female, they did not call me sir.
Others in this thread are right, for those of us pre everything, if we wish to be identified as female, we have to go the extra step to look the part.
I've been out of the house three times now fully dressed head to toe. And let me tell you it was exhilarating! Especially the last time. Had (wanted) to go to grocery store to get an apple pie for my wife. I was in wig, makeup, nice shirt, boot cut jeans, wearing forms, and a nice 3/4 length pea coat. Walked right in the store, got what I needed, and loved it.
Until I'm on hrt, my outfit just requires a little extra makeup and clothes (i.e. makeup, wigs, & forms). Worth it!
