Paper garments? (5)
I believe the answer is:
slips
'paper garments?' is the definition.
'slips' can be an answer for 'garments?' (slip is a kind of garment). I'm not certain of the 'paper' bit.
'paper garments?' is the wordplay.
'paper' becomes 'slip' (slip is a kind of paper).
'garments?' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'slip'+'s'='SLIPS'
Can you help me to learn more?
(Other definitions for slips that I've seen before include "They try to catch you" , "errors" .)
