I love the way this feels on the skin very soft, not to sure , only issues with this item is the arms are very small. I purchased a large , due to the fact that although my lower half is a size 6 to 8 i can run small to mediums lower, my upper half still has yet to get with the program  and remains large to extra large sizes, however my arms are tiny and it should not feel tight at all. I did go ahead and order the x-large though different color. We shall see how that fits any better in the arms. For now this one will be going to my daughter instead.
