Overpraising Cockney milliner in Scottish dance (10)

I believe the answer is:

flattering

'overpraising' is the definition.
(flattery means insincere or excessive praise)

'cockney milliner in scottish dance' is the wordplay.
'cockney milliner' becomes ''atter' ('hatter' - synonyms - said with the 'H' dropped - a cockney accent.).
'in' means one lot of letters goes inside another.
'scottish dance' becomes 'fling' (as in the Highland fling).
'atter' going into 'fling' is 'FLATTERING'.
