I haven't washed this item yet and that will be the final test.  Cancer has caused a big weight loss and I am cold most of the time.  This cardigan is just perfect.  It fits tight enough to keep in the heat; it moves with me and doesn't get in the way like a sweatshirt; it is light weight which has become very important to me;  if I tie the front it stays tied; and, it doesn't wrinkle.  I ordered the gray one and it is darker than pictured.  The sleeves are also slightly shorter than pictured, but I do have long arms and I like that the sleeves don't get in the way of washing hands or doing dishes.  I ordered the small.  I'm 5'7" and weigh 90 pounds and this fit perfectly with room to spare.  I would say it is true to size.  I am so pleased with this cardigan that I ordered two more.  Let's hopethey wash well!
