Flattering fit
Color: Dark Green, Size: XX-Large
This sweater is thick and stretchy but holds a nice shape, and is flattering on the body. The sleeves are nice and long too, which I really appreciate, being a tall person... the button detail is a great addition. True to size. I haven't washed it yet, and I imagine, based on the kind of woolly knit it is, that this sweater will eventually pill... but for now I'm enjoying being cozy and stylish. The deep green color is almost black green. I LOVE IT.

Love it
Color: Dark Green, Size: Small
I got the dark green. Love the sweater and it's warm. I do layer the sweater as well. It is as pictured. Size is perfect to me. I like sweaters to be longer and a bit wider in case it is freezing and I need to layer it. This sweater is perfect for layering. It comes closer to my backside, it is a little wide and not snug, and I like that the sleeves come over my wrists

Still soft but looks terrible after 1 wash. Save your money
Color: White, Size: Small, Color: White, Size: Small
Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

Disappointed.
Color: Blue, Size: Large, Color: Blue, Size: Large
This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.
