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.
