Poshak (पोशाक), also called Vāstra (वस्त्र)[1] is the Hindi term used for the complete attire used in the vedic period. As mentioned in Sanskrit literature and Buddhist Pali literature during the 6th century BC, the costumes belonging to the Vedic and post-Vedic period 1500 BCE to 350 BCE consisted of the antariya, which is the lower garment, the uttariya, which is a veil worn over the shoulder or the head, and the stanapatta, which is a chest band. The modernday Sari is one of the evolved poshak earlier known as Sattika (which means women's attire) that was single garment to wrap around the waist and cover the head.[2][3][4][5][6][7][8][9][10][11]
