For me, it’s the clothing I wear. Like when I worked out, I used to wear standard masc workout clothes. But once I discovered sporty fem fits that I look good in, I loathe whenever I have to wear my masc clothing. I like how I look with fem clothing so much more.
I also started growing my hair out and once I saw how I looked with it, I cannot go back to short hair anymore. The simple thought of going back to short hair makes me feel so dysphoric. Plus the compliments I get about my curls which certainly helps.
