All the hair colors, styles, and facial features are gender neutral in Animal Crossing, AND you can apparently change any of those feature on the fly whenever you want
New Leaf already had all the clothes be gender neutral as well so they'll probably stick with that
Animal Crossing New Horizons is the true gender expression game we need
