A support device for a wearer is provided, including an anchor member, a first strap and a second strap. The anchor member is fittable around the torso of the wearer. Each strap has a first end and a second end and connects to the anchor member at the first and second ends. Each strap has a shoulder-engaging portion that is shaped to engage a shoulder joint of the wearer. The straps are each adapted to carry a tensile force and thereby exert a rearward force on the shoulder joint through the shoulder-engaging portion. The straps are configured to engage the shoulders of the wearer no further medially than the acromioclavicular joints. Each strap extends along a path that, in use, does not cross over the anterior axillary folds of the wearer.
