I wear a size 12/L in top and bottoms, I have big arms so I was apprehensive about ordering a Large so I went with an XL and I'm so glad I did. it's a perfect fit, it's roomy, soft, comfortable, lightweight, and it has some stretch. Oh, and the hoodie part, oh my, it covers my whole head, I love it on windy days.
I'm going to order in more colors.
