This pajama set includes a long-sleeve shirt and matching long pants in a relaxed fit. The woven poplin fabric is made from cotton and polyester, giving it a smooth surface and a structured feel. The shirt has a collar, front button closure, and buttoned detailing, while the pants sit at a mid waist and fall in a wide-leg shape. The striped pattern and straight silhouette give the set a clean, basic look for indoor wear.
