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.

Super cute, highly recommend
Color: Beige, Size: Small
Absolutely love this sweater, I purchased a size small and it fit perfectly. It’s very soft and can be worn with a button up shirt underneath or by itself. It was true to color and was white and black. Just like the picture showed. It’s not super warm by itself, but with a shirt underneath much warmer.

Light, soft sweater
Color: Beige, Size: Small, Color: Beige, Size: Small
I liked this sweater so much, I bought it in other colors. This review is for the brown sweater, which is a warm brown color. I wear colors in the cool color palette, including cool-toned or ashy browns (see photos for comparison), but decided to keep this sweater to wear in the Fall. Color reminds me of milk chocolate. These are my go-to sweaters! Easy to pop on and wear with jeans or slacks for a put-together look. I normally wear a US Medium, but I returned for a Small. You may want to size down. Sweater is soft and comfortable, quality is great, and the weight is light and perfect for Spring or Fall. They have washed well, and I have dried in the drier for about 10 minutes before removing to finish drying on a rack.

Love it so much!
Color: Beige, Size: Small
This is super cute! Beware the ‘beige’ color is very much a white sweater with black stripes so one star gets taken away for that. Go figure. But otherwise super cute. Cropped so beware of that but good quality!
