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.
The shirt is so soft and oversized, I absolutely love it just ordered a Bad Company sweatshirt just like this one. The price is a little high I must say but I seem to manage to find a 20% off coupon every time I order.
