I think I wore it about twice. ◯ There are two buttons in the front. ◯ The collar, hem, and cuffs of the wrists appear to be single-layered at first glance, but they are all subtly double-layered. ◯ I took a picture with the collar slightly spread out so you can see the double layer, but it's subtly double-layered with gathers, making it a softly stylish tailor. ◯ It looks somewhat neat and stylish. ◯ Thin, see-through. ◯ There are gentle curved seams down the center of the back and on the left and right sides of the front and back panels, creating a sleek silhouette. ☆ The size is listed as M, but the shoulders and arms are comfortable even for me, who usually wears L, so I think it would fit someone who wears L as well. However, the width is 50cm, so the buttons almost didn't close on me, who has a large bust, and I wore it as a cardigan. ☆ I didn't notice it until I took the photos, but there are two red lines, about 1.5cm long, on the upper part of the right sleeve, about 10cm from the cuff, possibly from a clip. It's barely noticeable. This is how it looks when the photos are brightened.
