A friend of mine had seen me wearing braces around my shoulders and so bought a pair himself but let them hang down. I told him they're meant to keep your pants up. He was trying to make a fashion statement. No harm in that. I saw a person doing the same thing once in Hollywood. The idea of braces being worn hung down loses their purpose, but the way pants are made, they fit snug around one's waist without the need of braces or sometimes even a belt. I always wonder whether braces had any purpose in the 20s and 30s. But back on topic, they'd work well in a physical labor setting.
