This item was purchased just last month. I wore it once, but I've decided to sell it because I bought something similar. The size is L, and the back is elastic. The fabric is soft, so I think it's comfortable to wear. It's very difficult to describe the color, but I think the actual color is lighter than in the photos. It's a light, dark blue, and I feel like there's a bit of gray in it, but please understand that this is just my personal impression. I will fold it up small for shipping. Thank you.
