Most undressed are almost wearing top (6)

Ross

I believe the answer is:

barest

'most undressed' is the definition.
(the most bare)

'are almost wearing top' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'wearing' means one lot of letters goes inside another.
'top' becomes 'best' (similar in meaning).
'are' with its final letter taken away is 'ar'.
'ar' inserted inside 'best' is 'BAREST'.

(Another definition for barest that I've seen is " Merest".)

I've seen this clue in The Telegraph.
