The Petite medium top is rayon & nylon and accented with lace and clear sequins. The pencil skirt is a 12P with a back slit and the jacket is 14P. Both are 99% cotton & 1% spandex and fully lined…love the subtle paisley design in this fabric. Only worn a few times to special occasions and purchased in 2006. The scalloped sleeves on the jacket are 3/4 length and may be worn cuffed or down. And the buttons are very chic!
