This knee-length balloon dress was purchased for a ceremony. I've worn it twice, but I'm selling it because I no longer have an occasion to wear it. It's size 11, but I think it would fit someone who wears a size M to L. The hem has buttons that allow you to adjust the length and balloon shape, and it will have more volume if you wear a petticoat. Even though it's sleeveless, you can wear a long-sleeved inner layer underneath, making it suitable for all seasons.
