Well I mean tags like ok now here is more subby bree who acts a bit uncertain but knows what they do, and still expect partner to obey. (but you need combo of cloths and tf) Like uncertain dom but who would still do their own thing. Would be a pain to add as normal interaction. But as event which you can trigger if you wear espeon themed clothes with umbreon you would be able write scene for this. no need even add more versions of this scene because it is specific one off with specific stats.
But currently actually using pills for experimentation is easier than clothes. It is just less clicks 3 in smaller list vs 5 in huge list. yes you can reduce it to 3 later in the game but still 1 list is too big for all clothes compared to pills. So having quick equip for outfits, or splitting list, or using table inventory. because right now actually pills is faster way to experiment with scenes.
