Is nude ordering lingerie? (6)
I believe the answer is:
undies
'lingerie?' is the definition.
(undies is a kind of lingerie)
'is nude ordering' is the wordplay.
'ordering' is an anagram indicator.
'is'+'nude'='isnude'
'isnude' with letters rearranged gives 'UNDIES'.
(Other definitions for undies that I've seen before include "Knickers (abbrev.)" , "linen" , "Lingerie -- is nude (anag)" , "Used in (anag) -- unmentionables" , "Pants" .)
