The girl gets an assortment of set papers (6)
I believe the answer is:
sheets
'papers' is the definition.
(sheet is a kind of paper)
'the girl gets an assortment of set' is the wordplay.
'the girl' becomes 'she' (I've seen this in another clue).
'gets' is a charade indicator (letters next to each other).
'an assortment of' indicates an anagram (I've seen this in other clues).
'set' is an anagram of 'ets'.
'she'+'ets'='SHEETS'
(Other definitions for sheets that I've seen before include "Bedclothes, sailing ropes and paper" , "Leaves" , "Bed covers" , "Sail-ropes and bedclothes" , "They get blanket coverage" .)
