The perfumes came back from Sam or Alex (6)
I believe the answer is:
aromas
'the perfumes' is the definition.
('aroma' can be a synonym of 'perfume')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for aromas that I've seen before include "Spicy fragrances" , "Usually pleasing smells" , "Distinctive odours" , "Sweet smells" , "Smells, pleasant perhaps" .)
