Depending on how comfortable you are with your body, you may want to wear a binder, breast forms, a gaffe, or a packer. These are all garments or items that are used by transgender people to alter their appearance temporarily, depending on what parts you have. Binders are used to make a person’s chest appear flatter, while breast forms and a bra are used to augment it for those without them. A packer creates a “bulge” in the genital area, while a gaffe is used to “tuck” genitals for those who want a flatter appearance in that area. A person who previously wore more feminine clothing can begin to wear men’s flannel, or cut their hair to feel more androgynous. A person who previously wore more masculine clothing can take more care styling and growing out their hair or using more jewelry to define themselves. In these ways you can express your identity without facing the discrimination of “appearing” transgender. Of course, if you want to go full throttle with the clothing change, that’s totally valid. Just stay safe, especially if you’re trying to look more feminine.
Unfortunately, most countries in Western society only recognize binary genders when it comes to gender markers, and changing them usually requires proof of gender reassignment. It may cost money, often upwards of $100, to change your name legally.
Outside of the binary he/him and she/her, there are many non-binary pronoun sets, with the most popular one being the gender neutral singular they/them. People have also proposed new sets of non-binary “neopronouns”, such as xe/xir and ne/nym. Some people use multiple sets of pronouns, others don’t care which pronoun is used and others forgo pronouns altogether. You could have your pronouns as he/her/they if you felt like it!
