Frankie maybe losing capital in urgent look for business (5,8)
I believe the answer is:
power dressing
'look for business' is the definition.
(dressing a certain way in business)
'frankie maybe losing capital in urgent' is the wordplay.
'frankie maybe' becomes 'Howerd' (British actor Frankie Howerd).
'losing capital' means to remove the first letter.
'in' indicates putting letters inside.
'urgent' becomes 'pressing' (synonyms).
'howerd' with its initial letter taken away is 'owerd'.
'owerd' going within 'pressing' is 'POWER-DRESSING'.
(Other definitions for power dressing that I've seen before include "(Of women) donning clothes to look authoritative" , "what some businesswomen adopt" , "Style perhaps adopted by women executives" , "Wearing of severely tailored suits by some women executives" , "Wearing of clothes designed to give an impression of authority" .)
