Informally, the place for men of conviction? (6)
I believe the answer is:
scrubs
But I can't explain it at all! Could you help me understand?
(Other definitions for scrubs that I've seen before include "special clothing for those working in the theatre" , "Wormwood _____" , "Protective garments for surgeons" , "Abolishes" , "Clothing worn in an operating theatre" .)
