top is XS and bottom is medium but I would say small overall because the pants run small and the shirt is oversized and stretchy This is a women's cozy earth bamboo rib knit pajama top in size small. It features long sleeves and a classic design, perfect for lounging or sleeping. The top is in a lovely pink color and made from a soft knit fabric for ultimate comfort. It is a stylish and cozy addition to any sleepwear collection.
