Spick & Span dress (knee-length) I purchased this new at the store, but the size was a little small, and I hardly wore it. I kept it in my closet after washing it by hand at home. Color: Navy Size: There is no size listed, but I think it's S-M size. It looks slimmer than in the photos when worn. Material: 100% polyester. It's a thin fabric, like chiffon. There is no lining, but it's not see-through even when worn as a single layer. I think it can be used for everyday wear, and depending on the accessories and small items, it can also be used for parties and wedding receptions! My living environment has changed, and I haven't worn it much, so I would be happy if someone could take it.
