This is such a great dress! Perfect for end of summer, and wear it into fall with a denim jacket and high boots! The fabric tag has been removed, but my guess is that it’s silk with a touch of spandex - it’s quality fabric! Ellie Tahari - Fabulous little mini shift dress with two front pockets! S/M Approximate Flat Measurements: Bust: 18” Length: 29” from shoulder to hem
