This piece is very retro! It came from my elderly neighbor's home. I don't know if it is nightgown or a light summer dress. It is a light cotton fabric. No stains or flaws. The cute bodice material is so boho and the colors are retro. Its been washed and steamed and ready for a new owner! Great for summer. I've not seen anything like it in my searches...
