The colors are navy and off-white, the length is 86cm, it has no lining, and it's a stretch type that you pull over your head to wear. It's 98% polyester, so you can wash it in a washing machine at home by putting it in a laundry net. Worn 2-3 times, there are no stains. I bought it at H&M in Shinjuku. Because it has a navy geometric pattern, I think it can be worn both casually and formally. By the way, I am 151cm tall and weigh 40kg. It was my favorite dress, but I'm too old for it now, so I'm selling it.
