Tuck shop's last late shifts (5)
I believe the answer is:
pleat
'tuck' is the definition.
(I've seen this before)
'shop's last late shifts' is the wordplay.
'last' indicates one should take the final letters.
'shifts' indicates an anagram.
The final letter of 'shop' is 'p'.
'late' is an anagram of 'leat'.
'p'+'leat'='PLEAT'
(Other definitions for pleat that I've seen before include "that's tailor-made" , "Fold pressed or stitched into cloth" , "Type of fold in fabric" , "Crease" , "Double fold in a garment" .)
