Reine, that is definitively a $64,000 question!
When I started down this path I definitely thought that it was about the clothes. It was so exciting to assemble a wardrobe and that task definitely entertained me and continues to do so. Going out dressed was also exciting, first in fearing the worst and then in the realization that it wasn't really such a big deal.
As I learned more about "girl world" I realized that one thing I perceived but didn't consciously understand was the closer modes of social interaction that GGs take for granted. Male interaction always involves a certain level of aggressiveness and competition whereas females tend to cooperate and be more nurturing with each other. I have come to realize that preference for the latter mode of interaction is a part of my TG-ness.
I think that the clothes are a symbol of an ideal. I envy women their socialization ability. I'd love to be able to participate in that but as I cannot pass 100% I have zero chance of acceptance in the GG mainstream. The only thing that comes close is CDing events and of course the clothes can be a big part of that.
