Group of people gawping at her in gorgeous clothes (9)
I believe the answer is:
gathering
'group' is the definition.
(I know that gathering is a type of social group)
'people gawping at her in gorgeous clothes' is the wordplay.
'clothes' indicates a hidden word (the letters clothe the hidden word).
'GATHERING' is hidden in the letters of 'people gawping at her in gorgeous'.
'of' acts as a link.
(Other definitions for gathering that I've seen before include "Collecting" , "Assembly, meeting" , "Harvesting" , "Sewing" , "bee" .)
