Remarkably racy blonde is dancing (12)

Ross

I believe the answer is:

considerably

'remarkably' is the definition.

'racy blonde is dancing' is the wordplay.
'dancing' indicates anagramming the letters.
'racy'+'blonde'+'is'='racyblondeis'
'racyblondeis' with letters rearranged gives 'CONSIDERABLY'.

(Another definition for considerably that I've seen is " in a significant way".)

I've seen this clue in The Telegraph.
