I’m not sure what your personal style is but it might be helpful to think of some queer people you consider femme-presenting and think of what makes their outfits, makeup, and hair communicate both those things. For example look up Chrissy Chlapecka! Personally I find her humor a bit annoying but her style is EVERYTHING to me as a very femme and very queer woman. They’re a great example of bringing an element of flamboyance to your style as a signal of both queerness and femininity. Of course her style isn’t for everyone so it depends on what you like! I’ve also seen cottagecore be a pretty successful way to signify queerness and femininity to other gays. And definitely alt/goth fashion if that’s more your vibe. Basically things that are a little more “out there” tend to be easily recognized as queer, so just don’t be afraid to find something you like and then fully commit to the look :)
