It is interesting really. I feel like I was much more tied up in the clothing part of things pre-transition. Maybe because my body wasn't right so being able to 'present' as if my body was right by using clothing, makeup, hair/wigs, etc was helpful and felt good.
7 years later and with a more feminine body now, I still present very feminine in my clothing but I find I'm much less obsessed about it and I don't cling to it.
