Literally, "chinese shirt". This traditional Filipino male
garment is a loose cotton shirt with long sleeves and a round, open neck, with two or three buttons down the chest. It is typically plain white, although they can be found in peach, cream, or other pastel colors.
Adopted from the garb of Chinese sailors, this is the stereotypical work clothing of the Filipino farmer or fisherman, due to its wide availability and low cost. Westerners may see it most often worn by folk dancers performing the tinikling or other dances, or on waiters in native-themed restaurants.
It is also traditionally worn under the barong tagalog, for formal occasions, where the color of the camisa usually matches the color of the barong worn over it. Short-sleeved camisa de chinos are also sold for use under short-sleeved barongs.
I usually use mine as sleepwear (like loose, comfortable t-shirts).
The archetypical Filipino lower-class hero, Andres Bonifacio is most often portrayed wearing a camisa de chino, open at the neck, brandishing his trademark bolo (machete) in battle.
