bodice: [16] Originally, bodice was identical with bodies – that is, the plural of body. This use of body began early in the 16th century, when it referred to the part of a woman’s dress that covered the trunk, as opposed to the arms; and it soon became restricted specifically to the part above the waist. The reason for the adoption of the plural form (which was often used originally in the phrase pair of bodies) was that the upper portion of women’s dresses was usually in two parts, which fastened down the middle. In the 17th and 18th centuries the term bodice was frequently applied to ‘corsets’.

1510s, from hour + glass. Used 19c. in a variety of technical and scientific senses to describe the shape; reference to women's bodies is attested by 1897.
Men condemn corsets in the abstract, and are sometimes brave enough to insist that the women of their households shall be emancipated from them; and yet their eyes have been so generally educated to the approval of the small waist, and the hourglass figure, that they often hinder women who seek a hygienic style of dress. [Mary Ashton Rice Livermore, "The Story of My Life," 1898]
