This is an Unfil Egyptian Cotton Fine Gauge-Knit Vest. I believe it cost around 22,000 yen. It uses fabric from the Italian company Emilcotoni, made with GIZA 45, considered the most premium of Egyptian cotton. It has a luster due to its very long and fine fiber length, and has a very soft, supple, and elegant impression. It also has side slits, which not only make it easy to access pockets, but also create movement in the fabric, giving it a great atmosphere. As shown in the photos, the shoulders are slightly dropped, but they don't stick out and naturally fall along the shoulders. The size is 4, and the color is a dark navy that is almost black. It has only been worn a few times and is in very clean condition with no stains or scratches. It looks a little faded in the photos, but the actual item is not faded at all and is beautiful. It's rare to find, so please consider it if you're looking for one.
