Also known as: 裾結び, 系带衬衫
A Shirt tied together at the bottom, usually so that the Midriff is exposed.
Common examples include tying the tails of button-up Dress Shirt together in front, often just below the breasts, or tying the bottom of a T-Shirt around itself to show off the midriff.
This is not for a shirt's sleeves being tied shut individually or together. For that, see Sleeve Tied Shut, Sleeves Tied Together, or Clothes Around Waist.
