I have tuxes ordered just to be thorough (10)
I believe the answer is:
exhaustive
'to be thorough' is the definition.
(synonyms)
'i have tuxes ordered' is the wordplay.
'ordered' indicates anagramming the letters.
'i'+'have'+'tuxes'='ihavetuxes'
'ihavetuxes' with letters rearranged gives 'EXHAUSTIVE'.
'just' is the link.
(Other definitions for exhaustive that I've seen before include "Thorough" , "Comprehensive" , "all-embracing" , "trying out all possibilities" .)
