A sari is a piece of clothing that South Asian women often wear. If you go to a wedding in India, you'll probably see the bride wearing a red silk sari.
A sari consists of one very long piece of fabric that's wrapped around the body and draped over a shoulder, and garments worn underneath, including a short-sleeved blouse. The style and fabric of a sari, as well as the way it's worn, varies between different regions and traditions. You can also spell this word saree. It comes from the Hindi sari and the Sanskrit root sati, "garment" or "petticoat."
