Lack of judgement from Einstein — dress wrinkled around top of collar (14)

'einstein dress wrinkled around top of collar' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.

'lack of judgement' is the wordplay.
'lack of' becomes 'in' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'judgement' becomes 'discreetness' (discreetness is a kind of judgement).
'in'+'discreetness'='INDISCREETNESS'

'from' is the link.
