" But if you want to comment on ridiculous clothing for an adult then let's at least be consistent "
Why? Genuine question. Because I really don't see why my taste needs to conform to someone else's ideas.
Each person should be free to comment on any garment, adornment or grooming procedure in the way they want to, and without having to pass a consistency test.
It does mean that there will be negative comments as well as positive ones. But if people want to know what others think, then that's part of the deal.
