It takes two to tangoyou and this Isadora Tango Red Stretch Polyester ITY Single Jersey! The acronym ITY refers to the interlock twist yarns that make up this jersey, which adds elasticity as well as a cool, soft feel overall. Fluid and airy with a generous 75% widthwise stretch, design flowy maxi dresses, effortless tunics, or close-fitting leggings and bodysuits. While translucent, particularly when stretched, a lining is not necessary for most projects.
