A cotton blend rib weave is calendared, or pressed through high-temperature rollers, to create the subtle, marble-like striations of Riva Moiré. This finish, which harkens back to medieval times, essentially crushes areas of the fabric to create an elegant, shimmering surface. The moiré effect changes depending on the angle, and due to the nature of the process, the effect is non-repeating and more obvious in some colorways than in others. This striking plain is available in fetching hues from jewel tones to nuanced neutrals.
