Clothing workers? (5)
I believe this is a double definition.
'clothing' is the first definition.
(shift is a kind of clothing)
'workers?' is the second definition.
(I've seen this before)
(Other definitions for shift that I've seen before include "Team of workers" , "Change position" , "Dislodge" , "Time when group of people are working" , "Move; garment" .)
(Other definitions for tailors that I've seen before include "Workers" , "Designers" , "They make fitted clothes" .)
