Not available, shocking pink cloth (6)
I believe the answer is:
napkin
'cloth' is the definition.
(I've seen this before)
'not available shocking pink' is the wordplay.
'not available' becomes 'na' (abbreviation).
'shocking' is an anagram indicator (letters shocked or shaken).
'pink' anagrammed gives 'pkin'.
'na'+'pkin'='NAPKIN'
(Other definitions for napkin that I've seen before include "Cloth used at mealtime" , "Protective cloth square worn during meals" , "Cloth square used to protect clothing while eating" , "Cloth square worn while eating" , "Small piece of table linen" .)
