Piece of furniture used for outfit with hesitation (7)
I believe the answer is:
dresser
'piece of furniture' is the definition.
(dresser is a kind of piece of furniture)
'outfit with hesitation' is the wordplay.
'outfit' becomes 'dress' (I've seen this in another clue).
'with' means one lot of letters go next to another.
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'dress'+'er'='DRESSER'
'used for' acts as a link.
(Other definitions for dresser that I've seen before include "One covering up" , "Person working in one theatre" , "Item of furniture - actor's assistant" , "Wardrobe assistant" , "clotheshorse?" .)
