This dress is so adorable. It is super stretchy and can be worn so many ways. It is 93% polyester and 7% spandex. And it’s nice and thick and forgiving with it. It’s cut. It would be so great with tights and a blazer and pumps in the winter. And in the summer, it would be cute with stray sandals, and a light wrap. It’s really fun. It would also look cool with a pair of gogo boots. The under arm two under arm is approximately 19 inches across the front but stretches too about 22 inches. The length is 37 inches. It has a lot of stretch.
