Super clean and streamlined, the tunic of the season is an indispensible summer staple, ready to top skinny jeans or leggings. The spice is in the details, from a mandarin collar to the shirttail hem to the fiery hue (or classic white, if you prefer). Pull-over style with button placket. Long sleeves. Tunic length. Pure Irish linen. By Eileen Fisher. USA.
