Strip clubs opening from tomorrow (6)
I believe the answer is:
divest
'strip' is the definition.
(synonyms)
'clubs opening from tomorrow' is the wordplay.
'clubs' becomes 'dives' (I have seen 'Seedy clubs' mean 'dives' so perhaps 'clubs' could also mean 'dives').
'opening from' suggests taking the first letters.
The initial letter of 'tomorrow' is 't'.
'dives'+'t'='DIVEST'
(Other definitions for divest that I've seen before include "Strip off clothes, take away" , "Strip (someone of clothing)" , "Undress" , "Relieve (oneself of garment)" , "disrobe" .)
