It's a compromise. Clipping is there to keep the visual consistency of the race(s). Think of viera, they (SE) could just hide the ears, and then hats would be available. Instead of doing so, they have kept ears visible, to stay consistent. The compromise is no hats.
I choose to play a tailed race as well, I glamour around the tail; I do not wear outfit pieces that look jarring due to clipping. If I can't wear a few pieces: so be it.
