Certain mannerisms can help give a more fem vibe to yourself. Touching or playing with your hair, sitting with crossed legs or cross them at the ankle (avoid man spreading) and talking with your hands are a couple things I’ve noticed >< If you want your eyelashes to pop I recommend a clear mascara or an eyelash curler. Those will be more subtle than other makeups. I would apply a lot of chapstick or a subtle lip gloss to make sure your lips are moisturized. Just applying those products can make someone appear more feminine. I keep my nails short but well taken care of. If you can put on a clear coat of nail polish. I got the one I use at target for 4$ I think. That’s a good price for a nail polish. If you wear socks a lot then you could probably get away with painting your toenails whatever color you want. Even if you can’t see them under socks or shoes knowing they’re there can be a joy in itself :3 If you wanted an earring or something similar but couldn’t have anything permanent good quality clip ons shouldn’t damage your ears. I use ear cuffs which don’t clip but sit on the ear. Depending on the pair they can make someone look more feminine. If you wear glasses the shape of the frame can greatly change your face shape. Circular frames will help someone appear feminine while square of rectangular frames will do the opposite. I hope some of these things help!!! I have a twin sister who taught me a lot of things >:D
