One goes with hose that’s found in gutter (7)
I believe the answer is:
doublet
'one goes with hose' is the definition.
(historical garment worn with stockings or hose)
I don't understand the rest of the clue.
(Other definitions for doublet that I've seen before include "Former male, close-fitting body garment" , "would be seen in battle" , "Formerly, a man's close-fitting jacket" , "Old garment worn with hose" , "Jacket once, went with hose" .)
