Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.

Nice cozy sweater, but handwashing is recommended
Color: Beige, Size: Medium
Soft and cozy, but does not wash well. Goes with everything. This sweater fits well and looks great. I received lots of compliments while wearing it.

Great sweater for winters in the Midwest
Color: Black, Size: X-Large
Love this sweater! I went back and got another color! The fit is true to size and very comfy. The button detail on the sleeves just adds a little pizazz. The weight of the sweater is perfect for winters in the Midwest.

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
