Fabrics Great, Size a little Big, Overall Pretty Good
Size: Medium, Color: Dark Navy
This suit was truly great, the size for the pants and the vest were pretty on point, maybe a little long for the pants. The jacket was way too big though compared to the rest. Overall pretty good suit for the price, very surprised at the build quality and faabrics.

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.
