'get smart' is the definition.
I can't tell whether this definition defines the answer.

'cast is stormed by crowd?' is the wordplay.
'cast' is an anagram indicator (letters are dispersed or cast around).
'by' means one lot of letters go next to another.
'crowd?' becomes 'press' (to press can mean to crowd around).
'is'+'stormed'='isstormed'
'isstormed' anagrammed gives 'dresstoim'.
'dresstoim'+'press'='DRESS TO IMPRESS'
