Chemisette & Plastron

A Chemisette (from French, "little chemise") 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 to the waist or upper arm.

The Pastron is an article worn to protect the chest in fencing and as part of some military uniforms. The name comes from the protective underside of the tortoise.
