What would be the best arm brace for a clavicle fracture?

Brace ??: The idea is to draw the shoulders back so the clavicle remains in proper position to heal. This is accomplished in some with a figure 8 Ace wrap looping both armpits & crossing in the back or a "clavicle strap" designed for this process. Arm slings are sometimes offered to rest the affected arm as a reminder not to use it. I have never heard of bracing the arm for this injury.
