Loose fit, blouson look, batwing sleeve with wide stretch band around the bottom, wear it long or short. This one size top will fit to an 18. Overall length from nape of neck to hem is 28" and full length and you can adjust to fit at hip as shown in picture. Measured across the front from under arm to under arm is 40" but it tapers in and you don't go about with your arms outstretched so this is indicative of the overall width.
