EXCLUSIVE AT NET-A-PORTER. Tibi's take on the classic button-down shirt is part of a consciously created summer capsule. Cut for a loose fit from 'Eco' cotton-poplin that's certified organic, it has utilitarian pockets and a chunky silver zipper that runs down the back. The crisp white hue means it'll go with almost everything in your wardrobe. Shown here with: [Tibi Pants id1243682], [Wandler Shoulder bag id1236629], [Porte & Paire Sandals id1240774].
