Daughter into Lauren modelled clean clothes (7)
I believe the answer is:
launder
'clean clothes' is the definition.
(I've seen this before)
'daughter into lauren modelled' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'into' is an insertion indicator.
'modelled' indicates anagramming the letters (letters modelled or shaped).
'lauren' anagrammed gives 'launer'.
'd' going into 'launer' is 'LAUNDER'.
(Other definitions for launder that I've seen before include "Clean, clothes or mafia money" , "Cleanse (material or money)" , "address the filth in lucre?" , "Wash and iron clothes etc" , "Led a run (anag)" .)
