I&Os are the items that make us feel modern, new, each season. It might be a shoulder that we are experimenting with, or a certain exaggerated sleeve shape. Pieces that makes us feel like our entire closet has been refreshed by their addition alone. And whilst they allow us to experiment, because they pair back with other items in our closet that speak to our DNA, we never feel in costume. We wear them for years, retire them, then bring them back out again when the time is right.
