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. Based on illustrations and written accounts, however, baro were still largely only worn by commoners during this period. They were mostly identical to precolonial baro and were made from opaque linen-like abacá textiles, and thus lacked the collars, buttons, and embroidery of later baro styles. 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.
