I've always been all over the place with my girliness.
During teenage years I wasn't overly girly, and neither were my friends. We were immediately post-hippy era and we just liked to wear "cool" stuff. But, I did dress up when going out, just not all the time. As a young career woman I opted for the sleek, polished, professional look but this was during the 80s when women wore business suits with wide shoulder pads. Not particularly girly either, but decidedly feminine. During the child rearing years I wore whatever I could wash 'n wear easily along with my kids' clothes. Jeans and Tshirts. But, I did still dress up nicely when my ex and I went out.
When I met my SO I was taking a lot of classes and dressed like the other college girls with jeans and cute tops. No sneakers though. I've always refused to wear sneakers outside of a gym, but still not particularly girly. But, when we started to go to alt clubs for drag shows and my SO was dressed, I went over the top girly (well, more like vampy), since I felt I was in competition with the young women who were there that I felt he admired. And I also ramped up the wardrobe, because I knew how much he admired nicely dressed women and I wanted him to admire me. I didn't do it because I felt threatened by his own presentation.
Lately though, I've been going through a lot of difficult stuff and I'm back to taking a minimum effort with my presentation. I still wear summer skirts and tops, but with easy flip flops and minimal jewelry and makeup.
I've always supported my SO no matter where I was along the girly spectrum. :p
