This is a J. Crew button down shirt made with green gingham fabric. This shirt was only worn once or twice and is in like new condition. This is a size 20. The chest measurement is approximately 25 inches. From the J. Crew website: "Less buttoned up, more low-key... Introducing the new shirt collection. Our design team spent months perfecting and wear-testing our new slim fit to get the silhouette just right. The perfect balance of sleek and easy, it's slim enough to tuck into your favorite pants and skirts without any uncomfortable pulling, tugging or bunching. And it's the details that make this shirt truly special—like the custom label, precise, refined topstitching, interior chambray piping and pops of blue button thread. Plus, we crafted it in organic cotton poplin with a hint of stretch for that just-pressed—but still supercomfy—feel. The cotton in this shirt is grown without chemical fertilizers and pesticides from non genetically modified seeds."
