A scoliosis activity suit includes a body-wrapping portion (10) and a correction portion (20). The correction portion (20) has a front segment (21), a rear segment (22), a shoulder-pulling segment (23), a chest-pressing segment (24), a pelvis-lifting segment (25), and a upper trapezius-pressing segment (26). The shoulder-pulling segment (23), the chest-pressing segment (24), the pelvis-lifting segment (25), and the upper trapezius-pressing segment (26) are formed on a front side of the body-wrapping portion (10) and extend to the rear segment (22) of the correction portion (20). To users with scoliosis, the correction portion (20) generates a 3D compression force on different portions of the spine of the user, such that a backward pulling force against a protracted portion of the shoulder, an uplifting force against an inclined portion of the pelvis, and a pulling force against portions with spinal sidebend can be provided.
