subtle hints via jewellery

hello!

which symbols are subtle hints for being bisexual for you? I (w) am looking for subtle jewellery that matches my style (I‘d rather not wear color - I love silver jewellery) and further: I want to add something to my socials. I found something about crescent moons. Is this a thing? ☽☾

I look forward to hearing your tips and recommendations! I have my first ever girl crush and I want to give hints...

Thanks xxx
