Bodice

A bodice () is an article of clothing for women and girls, covering the torso from the neck to the waist. The term typically refers to a specific type of upper garment common in Europe during the 16th to the 18th century, or to the upper portion of a modern dress to distinguish it from the skirt and sleeves. The name "bodice" comes from an older garment called a "pair of bodies" (because the garment was originally made in two separate pieces that fastened together, frequently by lacing).
Origin.
In Europe, bodices are derived from the kirtle. A fitted bodice became fashionable in Europe around 1450.
Classification.
The same word is used to refer to several related concepts, some of which also have other names.
In one usage, "bodice" refers to a separate upper garment that has removable sleeves or no sleeves, often low-cut, worn in Europe from the 16th century to the 18th century, either over a corset or in lieu of one. To achieve a fashionable shape and support the bust, the bodice was frequently stiffened with "bents" (a type of reed) or whalebone. The bodice was separate from the corset of the time because the bodice was intended to be worn over the other garments, and the others were undergarments.
In another usage, particularly in Victorian and early 20th century fashion, a "bodice" (in earlier sources, "body") instead indicates the upper part of a dress that was constructed in two parts (i.e., with separate skirt and bodice, such as a ballet tutu), but of matching or coordinating fabric with the intention of wearing the two parts as a unit. In dressmaking, the term "waist" (sometimes called "dress waist" to distinguish it from a shirtwaist) was also used. During wear, the parts might be connected by hooks and eyes. This construction was standard for fashionable garments from the 18th century until the late 19th century, and had the advantages of allowing a voluminous skirt to be paired with a close-fitting bodice, and of allowing two or more bodices to be worn with the same skirt at different times. For example, a woman might wear the skirt with a matching high-necked bodice during the day, and later the same skirt with a different, fashionably low-necked bodice in the evening. One-piece construction became more common after 1900 due to the trend for looser, more simply-constructed clothing with narrower skirts.
"Bodice" continues in use to refer to the upper portion (not including the sleeves) of a one- or two-piece dress. The bodice of a dress was called the "corsage" in the 19th century.
Styles.
In earlier periods, bodices and corsets were laced in spiral fashion, with one continuous lace. Some bodices were laced in the back. In later periods, both were laced like the modern tennis shoe, with eyelets facing one another. This was more convenient for women who had to dress themselves. In the 20th century, lacing was replaced by elastic or other styles.
Padding, boning, and other techniques were used to keep the fitted bodice smooth while it was worn. Pregnant women wore an adjustable type of bodice, called a "jump".
Starting in the 16th century, women used detachable sleeves as a fashion accessory. A ruff or other decorations might be added. By the 18th century, women were wearing a variety of accessories, including fichus and partlets, with their bodices. 
In the 19th century, in parts of Europe, styles reflected local folk dress, so that the bodice in France was frilled, in Austria took the form of the dirndl, and in Bulgaria, it had a gold stomacher. Other styles seen in the 19th century include:
Today.
Bodices survive into modern times in the traditional or revived folk dress of many European countries (see, for example, Austrian dirndl or the Aboyne dress worn by Scottish highland dancers). They are also commonly seen today at Society for Creative Anachronism events or a Renaissance Fair.
Modern variants include the halter bodice and the Indian "choli".
