Aliasing thighhighs_only -> naked_thighhighs.
Reason: Either direction would probably work for this one. "only" is currently in use, but "naked (clothing item)" tends to be more common with other things. "only" kind of makes the tag look a little too exclusionary to me, when I think it's still helpful to add with certain items still being worn (like gloves or a scarf).
