Oh my God! I couldn’t agree with you more! Something I’ve been looking for the longest time was male hosiery, especially for Hiro!
You may or may not have seen me mention before that I have a fellow Anime friend who dances and she and I are always looking for items we can recreate certain ballet story plots (kind of like with Princess Tutu) for an RPG story we’re working on together. There are some really nice classical performance outfits for Victoria and such, but the ONLY thing I am able to find as far as males go is maybe Ode for Hiro for H3 and Pretty In Pink for the Gen 4 guys.
So yes, The Basic Suit is by far the best thing out there for self-customizable costumes and such that involve realistically fitting tights for both genders.
