Clothes from stores ultimately got sent back (4)
I believe the answer is:
togs
'clothes' is the definition.
('tog' can be a synonym of 'clothe')
'stores ultimately got sent back' is the wordplay.
'ultimately' indicates one should take the final letters.
'sent back' says the letters should be written in reverse.
The last letter of 'stores' is 's'.
's'+'got'='sgot'
'sgot' in reverse letter order is 'TOGS'.
'from' is the link.
(Other definitions for togs that I've seen before include "Clothes (informal)" , "costumes [STRINE]" , "Gear" , "Clothes (sl.)" , "Swimsuit" .)
