I got my ears pierced a while back and I've mostly worn easy to miss jewelry, but my SO got me these big dangly cat earrings for xmas and I decided to finally wear them. Still absolutely terrified to go into like a store or something but its been fun around friends and family. Its the most feminine thing I've done around people I've only ever presented very masculine to so its been kind of heartracing. No too bad reactions yet though so thats a good thing.
I know its not necessarily a bi thing to be more feminine but I've definitely avoided things like this in the past to "seem straight"
Those are fucking adorable, and props to you for having the strength to wear them, even if it's just at personal events! It can be a hard step to take, especially when you're so used to presenting yourself in another way.
They are wonderful! I like to present feminine when I'm dating a guy, or when I'm single. I only do masc if I'm dating a woman, but even then I'll get the mood to change it up :). Just be you, because you are enough <3
