The design of this style is oversized with a loose crew neckline. For a more standard fit choose a size down.
Measurements are flat measurements as indicated in the photo. For the full bust, waist, and sweep, measurement, double the number given.
I usually wear a small or extra small, but I bought a medium because the former sizes were sold out. I don't regret it—it's chic in its slouchiness. I love the sleeve length (long). The print is gorgeous in design, with distinctive colors (of course it's Bowie, so it'll be inherently gorgeous). Wear this oversized sweatshirt with flares and platform boots, and you're set.
