Muse short and long sleeve

Cozy ribbed knit set from ALO Yoga. Includes a top and shorts. Perfect for lounging. Bottoms are M. I can not see the top size. I don’t remember. Please look at picture for measurements. Pilling if closely inspected. I tried to show pictures. I tried using the pilling machine and nothing came off. Not horrible upon looking at it but if you look closely you can see the pilling.
