Thank you for viewing. The color is a very dark navy, almost black. I bought this at Uniqlo a while ago and wore it a few times, but I don't remember clearly, so I haven't included the brand. The waist button has a hook closure. I've washed it normally and left it as is; ironing may be necessary. I apologize, but I will be selling it as is. Please check the size in the images. I will fold it up small and ship it in recycled packaging.
