A white button down is nice to have, in our opinion. But a soft white button down? That's a plain necessity. Extra soft, breast pockets, and made with our double cloth so it's a real no-brainer. Our signature double cloth is made with 100% cotton so it's lightweight (but not see-through). Sophia, a local SF beauty and La Croix aficionado, is 5'9 and wears an Extra Small.
