Kacchera or Kachera or Kaccha (ਕਛਾ) are an undergarment for the lower body that is specially tailored for shalwar with a tie-knot naala or naada drawstring worn by fully initiated Sikhs. They are similar to European boxer shorts in appearance. It is one of the five Sikh articles of faith called the Five Ks, and was given from Guru Gobind Singh at the Baisakhi Amrit Sanskar in 1699. Kachera have been worn by initiated Sikhs (Khalsa) since a mandatory religious commandment given by Guru Gobind Singh, the tenth Guru of Sikhism, in 1699. Both male and female Sikhs wear similar undergarments. This is one of five articles of faith—collectively called "Kakkars"—that form the external, visible symbols clearly and outwardly displaying one's commitment and dedication to the order (Hukam) of the tenth master.
