Model seen among pretty people (4)
I believe the answer is:
type
'model' is the definition.
(thesaurus)
'among pretty people' is the wordplay.
'among' indicates a hidden word.
'TYPE' can be found hidden inside 'pretty people'.
'seen' is the link.
(Other definitions for type that I've seen before include "Print form" , "Category; use keyboard" , "Category, sort" , "Sort, classification" , "Class, kind or printed characters" .)
