The baro't saya is a traditional Filipino blouse and skirt ensemble. It originated in Spanish times, when native Philippine women were required to cover their upper torso. Throughout Spanish colonization this was the everyday attire of most Philippine women.
The baro or blouse is short-sleeved and collarless. It is usually made of sheer fabrics and at times is embroidered. This is in contrast to the saya or skirt, which is made of simple opaque plaid or striped cotton or sinamay. A tapis or wraparound overskirt would usually be added, and an alampay or panuelo would be worn with the ensemble to cover the bosom.
