Gaudy little skirts are popular with consumers (8)
I believe the answer is:
tinselly
'gaudy' is the definition.
(thesaurus)
'little skirts are popular with consumers' is the wordplay.
I cannot quite see how this works, but
'little' could be 'l' (abbreviation for little) and 'l' is found in the answer.
'popular' could be 'in' ('in' can mean trendy) and 'in' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tinselly that I've seen before include "like glitzy decorations" , "just for show?" , "Like gaudy present" , "Showily presented" , "Showy" .)
