Woke in seaside resort, topless (5-2)
I believe the answer is:
right-on
'woke' is the definition.
(both can mean alert to injustice)
'seaside resort topless' is the wordplay.
'seaside resort' becomes 'brighton'.
'topless' means to remove the first letter.
'brighton' with its initial letter taken off is 'RIGHT-ON'.
'in' acts as a link.
(Other definitions for right-on that I've seen before include "Absolutely correct" , "Trendy" .)
