As early as the 18th century and into the 19th and 20th centuries, the middle to upper classes of the Philippines found another way to make their Barong Tagalog even more fancy and to make their place in society more obvious and easy to distinguish. Likely inspired by European shirts, the well-to-do put pleats on their barongs. Pleats are said to have been in style until about 1930. Pleated barongs were revived at different points decades later in the 20th century.
