Not a sweatshirt but a tee shirt. This shirt runs true to size but not loose. If you want it to fit loose like the model the buy a size up. Made of 65% cotton with 35% Poly for the perfect blend. Sleeves have cuff/band at the wrist and Banded at the bottom but cut out slits on both sides. Sewn in V inset. Cute Tee with soft Velvety feel. I am wearing a size large in the photo!
