Easy and unstructured, this throw-on trench coat is made of lightweight cotton twill, so you can layer it over anything. Plus, all the seams are finished, so it’s just as clean looking inside. And, here’s a cool design detail: not only is the sash tie removable, so are the belt loops. Style Name: Madewell Sedgwick Trench Coat. Style Number: 6097949. Available in stores.
