A Chemisette is an article of women's clothing worn to fill in the front and neckline of any garment. Chemisettes give the appearance of a blouse or shirt worn under the outer garment without adding bulk at the waist or upper arm.
Chemisettes of linen or cotton were often worn with day dresses in the mid-19th century, and could be decorated with tucks, embroidery (especially white work), or lace.
The modern day chemisette was introduced in 2007 by "Chemisettes by Anne".These garments are meant to conceal cleavage, or chest scars. The chemisette includes a piece of fabric configured to extend between the two straps of the bra.
