A selection of travel items for the upper classes (5)
I believe the answer is:
elite
'the upper classes' is the definition.
(thesaurus)
'a selection of travel items for' is the wordplay.
'a selection of' indicates a hidden word.
'ELITE' is hidden within 'travel items for'.
(Other definitions for elite that I've seen before include "A privileged or superior social group" , "Superior or favoured group of people" , "A privileged class of people" , "Exclusive group" , "Group considered to have superior status" .)
