The Must-Have Shirt in Butterluxe is a relaxed fit button up that has an elegant drape, with shoulder seams that are slightly off the shoulder. Made with our light jersey knit blend of soft merino wool and TENCEL™ Lyocell with a touch of stretch, its silhouette is a little longer, making it a great layering piece to tuck-in or top pants and skirts. Just add heels to your look for instant elevation. Known for its lightness and versatility, TENCEL™ Lyocell is a man-made cellulosic fiber extracted from FSC and PEFC-certified responsible wood sources. Lenzing, the producer of TENCEL™ Lyocell, has achieved the highest rating from CanopyStyle for clean chemistry use and water recycling. Based on third-party certified lifecycle assessments, TENCEL™ Lyocell is over 50% less emissions intensive, compared to conventional lyocell.
