Zipper. 2 pockets 65% polyester, 30% rayon, 5% spandex Great little Joanie Christmas dress! It is indeed a small, but a generously sized small, so if you’re in between 2-4, this will likely not be for you. Would fit a small-medium, or someone hourglass shaped. As soon as I find my measuring tape, I’ll post pics, but if you’re closer to a 6, this is for you!
