occasion. In 1975, Marcos issued a decree for the barong tagalog, along with the baro't saya, to become the official national attire. June 5 to 11 was also declared as the "Barong Tagalog Week". Following Marcos' decree, barong tagalog became widely mandated as office wear for both employees of the government and private companies, as well as school uniforms. In the 1970s to the 1980s, companies like the Philippine Airlines, Ayala Corporation, and the Allied Bank were prescribing barong tagalog as their uniforms. Various semi-formal and informal versions of the barong tagalog developed during this period, including the short-sleeved polo barong and the linen barong. In 1998, Supreme Court Justice Hilario Davide, Jr. mandated the wearing of barong tagalog for all employees of the Judiciary of the Philippines.

Grooms now almost always wear barong tagalog, while women favored western-style bridal gowns. Types of material used The finest barong tagalog are made from a variety of indigenous sheer fabrics (nipis). The most common traditional materials used are listed below.

It has a fine lustrous silk-like texture and has a natural yellowish tinge. It is the most expensive and highly prized material for barong tagalog, due to its manufacturing difficulty, quality, and rarity. It is characterized by fibers of uneven thickness which gives the fabric the appearance of having streaks. Piña seda – a traditional fabric created by interweaving piña and silk (seda) fibers. It is usually less expensive than barong tagalog made purely from piña, but is more expensive than other types of material. It is characterized by piña fibers on the transverse weft, and silk fibers on the longitudinal warp. It is a lighter yellow color than barong tagalog made from piña. Jusi – a traditional sheer fabric hand-woven from abaca fibers. It has a polished texture and a natural off-white color. It is less
