Review things like fashion label worn by son (4,5)
I believe the answer is:
take stock
'review' is the definition.
(I know that review is a is a more specific form of the action of take stock)
'like fashion label worn by son' is the wordplay.
'like' becomes 'take to' (take to can mean to like or grow fond of).
'fashion label' becomes 'CK' (Calvin Klein).
'worn by' indicates putting letters inside (outside letters are worn by those on the inside).
'son' becomes 's' (genealogical abbreviation for son).
'taketo'+'ck'='taketock'
'taketock' placed around 's' is 'TAKE STOCK'.
'things' acts as a link.
(Other definitions for take stock that I've seen before include "Review a situation - assess holdings" , "Review situation or count assets" , "Appraise, assess" , "shop-lift" , "Make inventory or examine own position" .)
