Daring dancing stunned lasses (13)

I believe the answer is:

dauntlessness

I'm a little stuck... Click here to teach me more about this clue!

'daring' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'dancing stunned lasses' is the wordplay.
'dancing' is an anagram indicator.
'stunned'+'lasses'='stunnedlasses'
'stunnedlasses' anagrammed gives 'DAUNTLESSNESS'.

Can you help me to learn more?

(Another definition for dauntlessness that I've seen is " Perseverance".)

I've seen this clue in The Times.
