Getting my ears pierced was one of the first things I did. Just wearing a pair of simple silver ball studs, my everyday at-home wear, did a huge amount to reduce my dysphoria.
I initially got them pierced at a hair salon, where they used a piercing gun. I don't recommend that. The holes closed up. I eventually got them re-done at a tattoo shop. The guy looked scary, but he was scrupulous about cleanliness, even changing gloves between the left and right ears, and he did a good job.
Wherever you get them done, they will give you a set of piercing studs that you have to keep in 24/7 for 6 weeks while the holes heal. After that, you can change them to whatever suits your fancy.
At home, I wear the simple studs, even when I am out in the workshop hammering and sawing. It is amazing what a difference they make in the mirror! Going out, I like to wear dangly, sparkly earrings. However, masking during covid restrictions made me appreciate studs more. I have a whole box full of different earrings, including some rainbow and trans-flag earrings for when I feel like being un-stealth.
