I’m 5’5” and usually 150 lbs. I’m currently 6 months pregnant and really want to be comfortable. I would normally order a size medium. After reading reviews I decided to go up a size. I got a size large and it fits really comfortably with room to spare. I have worn/washed (hung dry) this sweater multiples times and it’s still very nice. I bought 2 colors and am happy I did.
