Smart I use as "bright" and "intelligent"
But, also aware of its meaning as a stinging sensation one gets with a dermal abrasion.
Common put down in my youth centered on that meaning.
"She's very smart."
"Yeah, where the skin's off!"
Also, when, say, someone has a coordinated ensemble I'd say "You look very smart." Which would be taken as meaning the entire look makes a particularly good impression.
The phrase is not heard often but the meaning is clear and the person to whom it is addressed knows exactly what's meant and is pleased.
