Pants and comes back to life? (6)
I believe the answer is:
Here is my best explanation:
This clue is a double definition.
'pants' is the first definition.
'comes back to life?' is the second definition.
(undead come back to life)
'and' is the link.
(Other definitions for undies that I've seen before include "Knickers (abbrev.)", "Used in (anag) -- unmentionables", "Undergarments (colloq.)" and "Lingerie".)
