The cut of the collarless part uses a slightly glossy material, making it very elegant and looking sturdy, instantly tightening the look and adding sophistication. I only wore it once for about 2 hours for an event, and I loved it so I kept it in storage. It's navy blue, but it's almost black. It will be very useful for school events and other occasions. I have inspected it myself, but there are no noticeable stains. However, please understand that I may occasionally miss something. It will be folded and shipped compactly, so please unfold it immediately upon arrival.
