Unisex sizing.
Ladies, order true to size for a fitted look, and 1 size up for oversized and cozy. 2 sizes up will give you a very oversized and boyfriend look. In the photos, Sara is wearing 1 size up and it looks "boyfriend" fit - she's usually a size small, and is sized up to a medium in the photos.
Men, size up 1 size for a very comfortable fit.
