This stunning sleeveless dress is a wonderful example of that. It has a streamlined design, with darts at the bust line, a hidden back zipper closure, and a dramatic cocoon shape midi skirt. It has a built in cotton lining, so no slip needed. I haven't been reaching for it recently, so I'm letting it go to make room in my closet. Feel free to ask me any questions about this lovely item. FYI all items from my closet come from a non-smoking, temperature controlled, but cat-friendly home. I'm a private seller whose appreciation for style is larger than her closet. Please note all items sold as is.
