This Isadora Lilac Stretch Polyester ITY Single Jersey certainly isn't li-lacking in style! 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.
