The Cat's Pajamas Lavender Check Luxe Pima Pajama Set. Luxe Pima is an ultra-soft, super light tightly woven cotton. It is of the highest quality fabric and, like voile, is ideal for warmer climates or for people wanting a light, cool sleepwear set. This pajama set has a roomy, comfortable fit. Most people find this brand's sleepwear to be larger than expected. This allows for a comfy fit and room for expected cotton sleepwear shrinkage, which is approximately 1" in width and length.
