Song Dynasty Straight Collar double-breasted gown with one-piece pleated skirt

The Song Dynasty straight collar, also known as the "mandarin collar," is a style of clothing that was popular in China during the Song Dynasty (960-1279 AD). The collar is characterized by its high, upright design that sits close to the neck and does not fold over like traditional collars.

This style of collar was often seen on formal attire, such as court robes and official uniforms, and was favored by both men and women. It was also commonly worn by scholars and intellectuals as a symbol of their status and education.

The Song Dynasty straight collar has remained an important element of traditional Chinese dress, and continues to be worn today in modern versions of the classic design. Its simplicity and elegance have made it a timeless style that transcends trends and fads.
