So many great things posted here, many of which I do. Leg, body-hair shaving, eyebrow shaping and dyeing, polished and shaped nails. Rings, bracelets and chains, sitting to pee! etc etc.
One of the first things I did is start wearing women's running shorts. They don't look way different from men's, somewhat different cut and shorter but did I feel free and feminine when I wore them on my daily runs out in public!
Music - absolutely makes me feel more feminine, Sarah Bareilles is one of my favs.
Bandanas tied in girly ways are one of my go-to's right now too.
