Frock in Andre's shop (5)
I believe the answer is:
dress
'frock' is the definition.
(I know that frock is a more specific form of the action dress)
'in andre's shop' is the wordplay.
'in' indicates a hidden word.
'DRESS' is hidden within 'andres shop'.
(Other definitions for dress that I've seen before include "changing gear" , "Adorn" , "Frock" , "formal wear" , "Robe" .)
