J.Crew Relaxed-fit Short-sleeve Baird McNutt Irish Linen Shirt S in Crisp Yellow. EUC. Less buttoned up, more low-key... Introducing the new shirt collection. Whether you're wearing it unbuttoned over your favorite tee, as a swim cover-up or just with jeans, this relaxed-fit shirt makes any outfit feel that much cooler. As the most oversized silhouette, it's meant to fit loose for an easy, laid-back vibe. And it's the details that make this shirt truly special—like the custom label, cuffed short sleeves and interior chambray piping.
