This simple plain go to dress is made of 65% Polyester and 35% Rayon. The fabric has a sort of box weave pattern to it that adds a bit of dimension and texture, very nice mid to heavyweight that holds its shape and is soft, the texture helps make the dress not see through. It will be a good casual dress to have for the fall, a comfortable dress that can be worn in winter and autumn. You also can really wear it year round.
