A treatment application garment, such as a glove or a sock, is disclosed. The garment allows for various treatments directed toward the fingers and toes, such as the fingernails and toenails. For example, each digit of the garment may contain an absorbent pad containing acetone. The hand or foot is inserted into the garment such that the nail is positioned below the absorbent pad containing the acetone, allowing the acetone to be constantly applied to the nail to remove polish therefrom. After the treatment is complete, the glove may be removed and the open end thereof tied off, thereby containing the acetone and the smell thereof within the glove. Other features and treatments are also disclosed.
