Size large From website: This shirt is the epitome of low-maintenance luxe. As a button-up, it's a classic wardrobe essential, but we love to wear it open as a spring/summer light layer. Our linen is made from 100% European flax, which is more sustainable and less resource-intensive to grow. Linen is the ultimate year-round fabric because it's breathable and naturally heat-regulating. Ethically woven from 100% European flax linen Breathable, durable, hypoallergenic, lightweight
