Organza is having a moment, and this midnight navy version is why. The sheer, crinkled weave creates extraordinary volume — three times the fabric of a standard scrunchie — so it piles magnificently or can be loosened into a cloud of gathered silk. Wear it at the crown for a statement top-knot, or loose at the nape for something altogether more romantic. The navy catches light like deep water, shifting between ink and indigo depending on the hour.
