So, the clothing system isn't just getting finished this time around, it's getting a few updates.
After all, if you've taken the time to get a dick, or god forbid, a huge dick, and then make the mistake of putting on a skimpy bikini, well. That may cause a bulge.
Not everything is going to be dynamically updated. In fact, very few things will be. Underwear will mostly be updated, as will tight clothes and skimpy clothes, but that's pretty much it. If you put on your lacy underwear, there's a bulge. If you then put on a long, elegant dress...no one will see it and it won't be reflected in your description.
The original plan was that clothing was ALSO going to update based on arousal, with or without the futanari trait, but sadly, that's far too cumbersome to actually do. Much as I'd like it to happen, there is just no way that I can reasonably write description updates for 500+ clothing descriptors. So, all you'll get is dick bulges.
