Zara dress features a v-neck, long sleeve, surplice top, banded waist and cross draping at the front. Dress can be worn off the shoulders, up on the shoulders (as shown in the picture). I will suggest sizing up if arms are a bit snug for comfort.
Model in the picture is wearing a 2X.
In terms of sizing a 1X fits 14/16; a 2X fits (18/20); 3X fits (22-24).
94% polyester, 6% spandex, hand wash with cold water.
