Very versatile shirt dress with a sophisticated style. Wear with Knee boots, Sandals, or Heels. Can wear as a cover up! Love this dress! Would keep but too small. Wear with belt to show of your curves, or without for a more care free loose style. Does not have a size or fabric content tag. Bought new and was sold to me as a that way. Can fit small to large depending on fit desired. I’ve included measurements. I would say it is silk or silk blend.
