Trousers Juliet intends to take top off (5)
I believe the answer is:
jeans
'trousers' is the definition.
(denim trousers)
'juliet intends to take top off' is the wordplay.
'juliet' becomes 'J' (phonetic alphabet: alpha, bravo, charlie etc.).
'intends' becomes 'means' ('mean' can be a synonym of 'intend').
'to take top off' means to remove the first letter (I've seen 'taking top off' mean this).
'means' with its initial letter taken away is 'eans'.
'j'+'eans'='JEANS'
(Other definitions for jeans that I've seen before include "(Usually) blue casual wear" , "Denim trousers" , "Trousers made of strong cotton, usually dyed blue" , "boys in France?" , "Are they worn by girls in Britian" .)
