That’s tricky. The 80s Eurythmics “Sweet dreams” Suit=Androgynous is mostly passe, although in cis culture it still oddly has impact. But it’s not androgynous and wasn’t then either.
I think you could go with some kind of cyberpunk victorian mashup of complementary styles.
While it still has a masculine lean, it’s quirky masculine 19th century lean and not instantly identifiable as masculine or feminine.
I’m ancient (45) – me at 18 in 1990. I never really cared if I looked masculine or feminine. Didn’t identify specifically with androgynous yet I’d have been fine with that designation too.
Was I a boy or girl? Been called both and either and neither. I mention cyberpunk because the brown leather in general usually lives comfortably across gender spectrum, imo. It’s the only leather jacket I had but I loved that people couldn’t tell if I was a boy or girl much of the time at first glance… and I wasn’t even trying for it. I just liked it.
