'trees' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'certain clothing to remove in' is the wordplay.
'certain clothing' becomes 'pines' (I can't explain this - if you can you should believe this answer much more).
'to remove' becomes 'strip' (stripping is a kind of removing).
'in' means one lot of letters goes inside another.
'pines' enclosing 'strip' is 'PINSTRIPES'.
