Get rid of clothes for all to see parasite (5)
I believe the answer is:
louse
'parasite' is the definition.
(type of parasitic insect)
'get rid of clothes for all' is the wordplay.
'get rid of' becomes 'lose' (I've seen this in another clue).
'clothes' is an insertion indicator (some letters clothe or cover others).
'for all' becomes 'U' (Universal film certificate - suitable for all).
'lose' enclosing 'u' is 'LOUSE'.
'to see' acts as a link.
(Other definitions for louse that I've seen before include "Nit" , "Parasite; nasty person" , "Wingless parasite" , "From cad" , "Rogue" .)
