Authentic Vietnamese traditional shirt bought in Vietnam

When I travelled to Vietnam in 2005 I had this shirt custom tailored for me. Sadly, the shirt no longer fits me. It's a beautiful soft material. The piece consists of two shirts, an undershirt and the beautiful designed outer shirt. The undershirt does have a little marking, so you could substitute it for a different shirt. There is no designated size, but, I wore a size 8 back then, so I would label this shirt as M.
