This is a two-piece Nagajuban (long undergarment) for year-round use. This convenient set includes a half-length undergarment and a skirt, and the half-length undergarment comes with a collar and an Emon-nuki (a loop at the back of the neck to adjust the collar). You can replace the collar with your favorite one. It can also be washed at home, making it useful for replacements. Since it's separate top and bottom, it's easy to move in, and it's a popular product that's easy to use. Sizes are available in M, L, and LL. Combinations of different sizes (for example, a size L half-length undergarment and a size LL skirt) are also possible, so please feel free to inquire.
