Lower garment (6)

I believe the answer is:
jersey
I believe this clue is a double definition.
'lower' is the first definition.
(type of cow, something which moos or lows)
'garment' is the second definition.
(jersey is a kind of garment)
(Other definitions for jersey that I've seen before include "One over the moon might have been such" , "Breed of cattle" , "tax haven?" , "whose yellow variety represents the cream" , "Woolly" .)
