Disclosed is a posture support garment. The posture support garment can be designed to use an elastic tension fabric that provides tension on the left sleeve and right sleeve of the posture support garment. The tension created can pull the back of the left sleeve and the right sleeve inwards towards the middle of the wearer of the posture support garments back. This, in turn, can cause the wearers shoulders to be pulled back and upwards, thus stretching the wearers chest and shoulder muscles while also relieving tension on the wearers back and neck muscles. This can help reverse the effects of repetitive poor posture as well as the physical pains associated with poor posture. The elastic tension fabric can be concealed beneath a back panel to the posture support garment which allows the elastic tension fabric to stretch and contract without affecting the appearance of the back panel.
