How do the size and shape change when turning the draped side and plain side inside out?

The outside is draped, and when turned inside out, it is plain. This top from THREE TO EIGHTY features a reversible design where the color and detailed design of the outside and inside are completely different^[1]. Rather than simply changing the color, the garment's dimensions and silhouette themselves change depending on which side you place on the outside.

The outer draped side is made with a total length of 56cm, shoulder of 43cm, and hem of 42cm, falling relatively comfortably while bringing out the fullness of the folds^[2]. The sleeve length is also generous at 65cm^[3]. On the other hand, the inner plain side has a total length of 53cm, shoulder of 38cm, and hem of 40cm, so the overall length becomes shorter and the shoulder width also narrows^[4]. The neckline is also cut into a wide boat neck, resulting in a simple silhouette that reveals the neck line and collarbones instead of folds^[5].

The chest measurement is the same on both sides at 40cm, so the basic width wrapping around the torso is maintained^[6][7]. However, compared to the draped side, the plain side's shoulder width and total length are reduced, and the sleeve width is subtly wider on the plain side at 14cm compared to the draped side's 13.5cm, creating a different fit^[8][9]. In clothes made by overlapping two layers, the inner side must be slightly smaller than the outer side so that the garment does not bunch up loosely and wraps around naturally. It is a structure where you choose whether to wear it generously by emphasizing the three-dimensional feel of the folds, or to wear it neatly by emphasizing the clean lines of the boat neck.
