Attractive girl at party with students (4)
I believe the answer is:
doll
'attractive girl' is the definition.
'party with students' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'with' says to put letters next to each other.
'students' becomes 'LL' (an abbreviation for learner driver written twice).
'do'+'ll'='DOLL'
'at' acts as a link.
(Other definitions for doll that I've seen before include "Figurine" , "Toy baby" , "Small replica of a person" , "Child's toy figure" , "Girl's toy" .)
