I have heard this somewhere --

"Never go on one's clothes."

Surprisingly, I haven't got even a single hit on Google

Does it exist and if not, does it make sense?

Appearances are deceptive.
Do not judge a book by its cover.
Clothes do not make a man.
All that glistens/glitters is not gold.

Which of these are critical in their tone?

1) Appearances are deceptive.
2) Do not judge a book by its cover.
3) Clothes do not make a man.
4) All that glistens/glitters is not gold.

None are critical, but are offered to a naive person in a manner akin to,

" Watch your step "
" Don't be conned ".

And how did we get to Let the buyer beware (caveat emptor) from "A person who has a pretty face and wears beautiful clothes may not have same kind of heart inside." I wonder?
