There will be places to buy clothing afaik. The intimate part cosmetics are also a thing, Mofu simply hasn't added items yet. Also about the prostitution part, I'm not sure if that would be a good idea because the game is not about administration, it's about collecting loot from enemies you fight.
Also it's a bit hard to say how much is done by now. A lot of people have been making a lot of requests and the game is currently demanding CGs more than sprites
