Lounie long-sleeved collarless jacket. It has no lining and can be worn casually, making it suitable mainly for spring and autumn. Since it is thin, it can also be used in summer to prevent sunburn. It is not a sheer material. The color is a dark khaki. I bought it but it didn't suit me, so I've only worn it 2-3 times. It has been home-cleaned. Perhaps due to the use of an iron, there are some color irregularities on the buttons (see photo 6). Please understand this before considering purchasing. Color: Green Season: Autumn, Spring
