What is the meaning of you're Never Fully Dressed Without a Smile?

The original music for Annie was by Charles Strouse and the lyrics were by Martin Charnin, including “You're Never Fully Dressed Without A Smile”, my favourite song from the film. ... Most lyrics tend to be about how much you love someone, or how sad you are that someone you like doesn't like you as much as you like them.
