This invention is directed to patients who need vertical support in the cleavage area due to symmastia repair or reconstruction of the chest cleavage for breast reconstruction after mastectomy. The support garment is designed not to support the breast or nipple area of the chest. The Y support which fits the patient close to the neck and between the breasts is attached to a full back panel using self adjusting velcro closures. This unique design creates a force much like a bow to provide constant pressure from front to back on the cleavage area only to allow scar tissue to form during the healing process. The cross link high density foam insert maintains even pressure during healing and does not lose its resiliency or permit permanent deformation.
