Sentimental slush — see right through the German beauty queen? (4-6)

'sentimental slush' is the definition.
The definition suggests a singular noun which matches the answer.

'see right through the german beauty queen?' is the wordplay.
I cannot really understand how this works, but
'see' could be 'look' (I've seen this in another clue) and 'look' is located in the answer.
'right' could be 'good' (associated in meaning) and 'good' is found in the answer.
'queen?' could be 'er' (abbreviation for Elizabeth Regina) and 'er' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
