I ordered this two sizes up (normally a M, ordered an XL) and it’s perfectly oversized and is even long enough to cover my 53 year old bum in leggings. Yes it will stretch out of shape if you’re not careful, this is the kind of sweater that grows throughout the day because it is 100% cotton. That doesn’t bother me as again, I’m just wearing it with leggings and Uggs around the house. Great weight, heavier than a long sleeved tee, lighter than a hoodie and loose enough to layer. Washed up nicely, laid flat to dry and then tossed it in the dryer with a damp towel to soften it up. I think this cotton sweater will be a great easy to pack layer for my upcoming trip to Hawaii.
