Breastplate

By around 1000 AD, solid plates had fallen out of use in Europe and knights of the period were wearing mail in the form of a hauberk over a padded tunic.

[5] In order to prevent the wearer from being cut by their own armour, the design featured outward turned edges that also increased stiffness.

The most notable people using this type of breastplate is Gajah Mada, which is reported by Sundanese patih as wearing golden embossed karambalangan, armed with gold-layered spear, and with a shield full of diamond decoration.

[8][9] In Kidung Sunda canto 2 stanza 85 it is explained that the mantris (ministers or officers) of Gajah Mada wore armor in the form of chain mail or breastplate with gold decoration and dressed in yellow attire.

[12] The hair-pipe breastplates of 19th-century Interior Plains people were made from the West Indian conch, brought to New York docks as ballast and then traded to Native Americans of the upper Missouri River.

[13] This is a silicone or similar type of plastic vest or torso-plate that is placed over the male performer's chest, to mimic a woman's breast or cleavage.
