I love these hoodies. Soft, comfortable, perfect weight and price. I am 5’2”, 110 lbs and normally wear a size Petite 4 (XS). I order the Small in this. On arrival it is wide in the shoulders, boxy, sleeves and length too long. By the second washing (cold wash, medium dryer temp) it fits exactly like a Petite XS, is even softer and cozier. I would say the size S shrinks about 2” in every dimension: length, sleeves, width. The shrinkage is consistent and the colors remain true.
