Gender is odd sometimes. I have known for a very long time that I am not female, no matter how many people told me otherwise. I knew I wasn’t male either, but for a long time I didn’t have the words to explain who or what I am. In ways I still don’t, nonbinary is an umbrella term for all of us who don’t fit into the gender binary.
I often find people get a little bit confused when I say I am nonbinary because they expect someone thin and androgynous with a crew cut and a beige wardrobe and it’s fine to be that but that is not who I am. I wear skirts and dresses and I describe myself as femme, because I look and dress in ways that are associated with femininity. Sometimes people find that hard to understand, and that’s ok, you don’t have to understand you just have to respect. There’s an Eddie Izzard quote I’ve liked for years that about nails my relationship with cloth, “They’re not women’s clothes, they’re my clothes I bought them”, to me that’s a perfect explanation. Clothes don’t really have gender, we often associate them with gender, but they don’t inherently have that.
