This is one of the things that greatly limits my forum participation, because the same conversation happens over and over every time a new user asks about it, and it's incredibly frustrating. A more mathematical discussion of this issue can be found here:
In essence, it always goes like this:
New user: Where's the male stuff? I need some large detailed male outfits that the market does not have.
Old users: There isn't enough because PAs are jerks who are witholding awesome male clothing from us because they hate money and success.
PAs: No, we're not. Big clothing sets are financially risky already, and male content sells half or less what female content does.
Old users: You're clearly lying because you hate making male things that don't suck. If you made male content as good as your female content, it would sell.
PAs: What about X male outfit I made that didn't sell?
Old users: Clearly it sucked, or it would have sold. QED.
Interjection by helpful person: OP, could you kitbash using outfits X and Y?
OP: I guess.
Old users: Kitbashing is the absolute worst. I want a full period-accurate historical outfit with photoreal textures for $5. And where is my male suit?
Other helpful person: What about these male suits?
Old users: They're terrible. Everything is terrible. It's a conspiracy to deny specifically me the things that I specifically want at the price I want to pay for them.
And then the thread gets locked.
Right now there's literally a user claiming that the meshing and texturing of an outfit is the hard part, so it should be easy to do a male version of any female set. If this were true I would have no job because the market would be overrun with recent art school grads. Rigging, morphing and correcting an outfit is massively more tedious and time consuming than the original mesh and texture, unless you've made a bikini. This is also why the market has a lot of bikinis, incidentally. They sell great and they're faster to make.
