The author of this post is requesting for gender fluid clothes , we need more clothing items as for representational purpose, so it would be accurate.
Coming to avatar , in sense of clothing items and facial features maybe ,I am guessing cause there is variety of hairstyles available in male avatar & female avatar as well.
But I guess its okay to have a separate slot for them, if nobody is offended in any way or if majority of people are requesting it for!
