Flexible, elastic item with holes (9)
I believe the answer is:
lithesome
'flexible' is the definition.
(I've seen this before)
'elastic item with holes' is the wordplay.
'elastic' indicates anagramming the letters (the anagram stretches or twists into a new form).
'with' says to put letters next to each other.
'item' after 'holes' is 'holesitem'.
'holesitem' is an anagram of 'LITHESOME'.
(Other definitions for lithesome that I've seen before include "Graceful" , "flexibility" , "slim and supple" , "Flexible" , "Willowy" .)
