Here is another beautiful example from JCrew:
The Jacinda Jacket on sale for $99.99!
It is available in black and honey glaze (pictured above and below).
A ladylike design with the softness of a sweater and the refined tailoring of a jacket. Merino wool in a 12-gauge double knit. Fitted. Three-quarter sleeves. Hits at hip. Import. Dry clean.
This is a great piece to have in your closet because it can be worn at work as a great substitute for a blazer. Because it's supposed to be a sweater as well it is incredibly comfortable and snuggly. The sweater/jacket really blends the best of both worlds together.
My favorite perk is that I can wear it under a heavy wool coat and not feel like a stuffed sausage (the way I normally do when I'm wearing a heavier sweater, like THIS ONE).
