Frustrate a proposed law over European lack of attention (10)
I believe the answer is:
dishabille
'lack of attention' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dishabille that I've seen before include "Being only partly dressed" , "revealing dress" , "scantily clad" .)
