dunno bout the first question.
For the second, you need to know people's traits. In order to invite someone, they need the exhibitionist trait. and probably a high enough relationship with your character.
enjoying this one quite well so far.
Some things I'd like to see more of/changed:
for male characters: it would be cool/nice if. . . just like some clothing options outright state "will hide hard-ons", it would be cool if some stated the exact opposite. That way if players are doing full on exhibitionist type shit, they'll have better ideas of what to go for.
For all characters: let me wear a jacket/outerwear as my sole top, lol
Not sure if its in the works but, some kind of "sprite" to gauge your character by? I mean, doesn't need to be fully detailed or anything, even a faceless outline for a body that can change shape as your character does, and shows a "simple" color scheme overlaid with the clothing options you have on.
