It is traditionally made with sheer textiles (nipis) woven from piña or abacá; although in modern times, cheaper materials like organza silk, ramie or polyester are also used.
It is a common formal or semi-formal attire in Filipino culture, and is worn untucked over an undershirt with belted trousers and dress shoes.
Barong tagalog (and baro't saya) were worn universally among Christianized lowlanders throughout the Philippines in the Spanish colonial period.
[7] Barong tagalog is a formal shirt usually made of sheer lightweight but stiff fabric known as nipis (usually woven from piña or abacá fibers).
[8][9][10] Barong tagalog can vary considerably in terms of design and material used, but they share common characteristics of having long sleeves, embroidery, being buttoned (halfway or straight down the chest), and the absence of pockets.
[11] However, the direct female counterpart of the barong tagalog is the baro't saya (or more formal versions of it like the traje de mestiza and the terno), and both share the same precolonial origins.
However, in the Visayas, aside from similar baro (which had shorter sleeves) and salaual combinations, men also wore colorful robe-like and coat-like variants that could extend to well below the knees (known as the marlota and baquero in Spanish, respectively).
Among Tagalogs, red dyes and gold trimmings were indicative of being a member of nobility (maginoo) or the warrior caste (maharlika).
[16] Early records of clothing in the Philippines during the Spanish colonial era from the 16th to the 18th centuries were limited, thus the exact evolution of the precolonial baro to the modern barong tagalog can not be established with precision.
The couturier Jose "Pitoy" Moreno has hypothesized that this transitional style of shirt was the camisa de chino of later centuries, which makes it a precursor to the barong tagalog.
Depictions of members of the principalia upper classes (including natives and mestizos) in the 18th century showed that they invariably wore European-style clothing.
However, they already displayed hallmarks of the modern barong tagalog, including being made of sheer nipis material, embroidery, long sleeves, and a loose silhouette with slits on both sides.
In this period, it evolved into the modern "classic" barong tagalog, being much shorter with less ostentatious folded collars, while still retaining the sheer fabric and other baro characteristics.
Baro worn by commoners also favored darker colors like brown or blue, usually paired with white silk pants.
[7] A commonly repeated but false belief is that the Spanish colonizers made the natives wear their barong tagalog with the shirt tails hanging out to distinguish them from the ruling class; its translucent fabric allegedly showing that the wearer was not concealing a weapon underneath.
Most commoners throughout the colonial period wore baro made from cheaper and more durable opaque textiles, while expensive nipis fabrics were worn mostly by the upper classes.
[7][4] Indios and mestizos, regardless of class, wore barong tagalog and European-style clothing depending on what they can afford and which were fashionable at the time.
The wearing of barong tagalog did have racial connotations however, since most people of unmixed European descent (the insulares, criollos, and peninsulares) retained their own dress styles and largely ignored native fashions.
[10][4][18] After the Philippine independence on July 4, 1946, Americana or a suit and tie continued to be the dominant formal wear, worn by presidents Manuel Roxas and Elpidio Quirino.
[10][3][4][18] 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.
[19] While the barong tagalog was now regarded as formal wear, it did not gain popularity as a wedding attire for grooms in the early post-war Philippines.
