Vietnamese Yếm refers to an ancient Vietnamese bodice used primarily as an undergarment that was once worn by Vietnamese women across all classes. There exists a modern variant called “áo yếm”, but the historical garment was simply called “yếm”. It was most usually worn underneath a blouse or overcoat, for modesty’s sake.
It is a simple garment with many variations from its basic form, which is a simple, usually diamond or square-cut piece of cloth draped over a woman’s chest with strings to tie at the neck and back.
