Hang top of dress on corner (6)
I believe the answer is:
dangle
'hang' is the definition.
(dangling is a kind of hanging)
'top of dress on corner' is the wordplay.
'top of' says to take the initial letters.
'on' says to put letters next to each other.
'corner' becomes 'angle' (eg a corner of a shape).
The first letter of 'dress' is 'd'.
'd'+'angle'='DANGLE'
(Other definitions for dangle that I've seen before include "wave" , "Suspend in front of Glenda" , "Hang so as to swing freely" , "Hang provocatively" , "Temptingly offer" .)
