I was surprised to receive this item- and find the cut of the body and arms very unlike other sweats I have purchased before. I ordered an XS, as from the photo and description- it was described as an "oversized" fit- but I don't find that to be true. I sized down so I could have a normal fit instead of the oversized- and I shouldn't have. Also- if you like your sleeves a bit on the longer end( like me- who sometimes wants to pull them over my hands if it's cold out,) this might disappoint. I am going to size up to my regular size S to see if it works better, and the sleeves are a bit longer than the XS.
