Better than expected!
After reading the reviews about it being oversized, I was able to get the right fit that I wanted. It is on the thinner end as far as sweatshirts go, but I tend to run hot so I was quite pleased that I got a long sleeve shirt that didn’t make me sweat. Now, let me tell you about the quality …. For some reason I thought the design was just printed on it, but it’s not! The “jolly” is sewn on, and the stripes don’t look cheaper. I love the red banding at the neck, sleeves and waist. It’s so comfortable, and I got compliments on it all night. I would definitely buy it, or any of their own sweatshirts, again!

Runs big. Fabric is nice. Love the color
It's a nice color of green and feels great. I ordered a medium due to the reviews. It's a larger than a normal medium so it's slightly too small. I usually wear XL and sometimes L. So, it does run big. I returned it but probably will order a L.

Cute sweatshirt but I returned it. It was way oversized.
