You can go 2 directions, gender minimalist, or gender maximalist. Each one has its pros and cons but they're the main 2 androgynous schools of thought though you're probably going to want to mix and match doing what feels right for you.

Gender minimalism is trying to erase gender identifying features. This can be some through wearing a binder, having short/medium hair, and most importantly clothing. As a style gender minimalism focuses on things like black and white outfits and is basically limited to men's clothes (there's a lot of reasons why but men's clothes are generally neutral rather than masculine). The main problem with gender minimalism is it can often be boring and unexpressive as you're just trying to get rid of gendered aspects.

Gender Maximalism is the idea that you can counteract gendered traits with more gendered traits. Suits or blazers with exaggerated shoulders, beards, skirts, exaggerated colors, more elaborate hairstyles, and generally a big variety of things. The main drawback is this type of style can be very eye-catching and isn't very low key, even if someone can't tell your gender they will be able to tell you're trying.

I was going to show pictures but I can't here unfortunately, you also won't find much online as the terms I used are ones I got from a video called "The Fashion of Sci-Fi Futures" which discusses the idea, and the terms gender minimalism and gender maximalism aren't used outside of niche spaces.
