How can I signal to other lesbians that I’m gay, without being too obvious or masc?

I have longer hair and I’m generally a more fem-presenting person with kind of an alt fashion sense. Most people assume I’m straight tho, and have zero idea how to tell if someone is gay either. Please help!

Edit: I would also like to say that I still live with my parents and I haven’t come out to them yet. Plus, I’m still in school and I’m afraid that pins,lanyards etc will attract more attention from other people(bullies and homophobes)
