Aware of standing close to terrific girl, awake (5-9)

I believe the answer is:

class-conscious

'aware of standing' is the definition.

'close to terrific girl awake' is the wordplay.
'close to' says to take the final letters (the 'close' to the word).
'girl' becomes 'lass' (lass is a kind of girl).
'awake' becomes 'conscious' (associated in meaning).
The last letter of 'terrific' is 'c'.
'c'+'lass'+'conscious'='CLASS-CONSCIOUS'
