The first time around, I missed the intent of the OP. I commented about being a "crossdresser" and not "crossdressed". For me, as soon as I step out of drab mode, I am crossdressed, which means panties. That doesn't mean I don't enjoy being dressed in other items, but it's definitely a boundary I cross when my first foot goes through the leg of my chosen panties for the day. It's a small but significant distinction for me.
