A crisp collared shirt from Eileen Fisher that is an essential for the wardrobe. With a fit that hugs closer at the shoulders and looser at the hem, this button-up top provides a relaxed silhouette. It features 5-inch side slits, a back yoke with center back box pleat, and river shell buttons. Wear it closed with some classy linen pants, or unbutton it and layer over a white tee and jeans.
