The material is linen and nylon, so it can be worn year-round. The back of the waist is elastic, making it comfortable. The size is 2, but it's roomy even for me, who wears a size 11. The color is black, but it's more of a charcoal black. I bought it about 3 years ago, but I haven't worn it since I bought something similar, so it's been hanging in my closet. I'd love for someone who likes Brocante to wear it.
