Perfect little set! Get both
Size: Small, Color: Porpoise
Such a soft sweater! You have to get the matching set! The quality is amazing and the material is nice and thick for those chilly days! The set feels like a more expensive brand so you get a good deal! I washed it and it did not shrink and the color did not fade. I hung to dry and the fabric still looks perfect!

Impressive style and quality!
Size: Large, Color: Chocolate
I was impressed by this ribbed crewneck sweater's quality and style. It's soft, comfortable and flowy without being shapeless. I love the back slit which ads a little chic. I chose the chocolate color which is a rich, dark cocoa. The sweater is true to size. The sleeves are slightly bell shaped which ads elegance. I highly recommend pairing this sweater with the matching cropped pants. Together it creates a lounging set that's casual yet elegant and ideal for travel. Highly recommend both.

Cute and Cozy
Size: Medium, Color: Chocolate
Normally I am hesitant to buy clothes off Amazon but I kept getting ads for this. I took the chance and bought this + the pants. I live in Michigan where winters get bitter cold. These are actually very cute and cozy. I wear one layer of thermals over it and my puffer coat but even without it, it's still warm. The size is fine I would say you are ok sticking with your regular size or sizing down. It is thick and stretchy too. I got lots of compliments on the outfit.

Shades of Sweater & Pants are Off
Size: X-Large, Color: Zephyr Pink
The color of the sweater and pants are not the same shade. Also, they are far from “cozy” and not as snuggly as I had hoped for. However the quality of the construction and material appear good.

Very cute! High quality denim.
I'm just gonna be honest with you ladies. These look and fit best on someone with a flat stomach, or more defined waist. Otherwise it is going to be hard to find a balance of how they slouch on the waist and the right amount of baggy. I'm 5'2, 150lbs, and the 27 fits me perfect and falls about 1 1/2 inch below my belly button. The length was perfect either straight with my Converse, or cuffed with my sandals.
