They are aware of the situation in fact and how many users were offended by lack of female outfits. I heard from the developers back when the lounge released that they were going to try to get female costumes, but that was around E3 last year, and like many things in Home, will probably never happen due to laziness, lack of time/resources or straight up not caring. Choose your pick of which one this falls under. Sorry I did try last year to help you ladies with this.
It made sense that it was only male, since that's all they had in the actual Beta when that space came out.
