This is a nice cardigan with a good fabric weight and stretch.
My ONLY complaint is how narrow the hip-line is...the hips should be WIDER than the waist, yet on this garment, they are not. This will not result in what you see in the photo, but rather a fold at the waistline.  It's a look that has been fashionable, just not the hour-glass look you see advertised.

To get the same look, I have to un-button the last few buttons at the hips (see photo). I often wear my cardigans like this to show off some color from the camisole I wear underneath in a contrasting or complementary color.  If you don't like that look, I suggest you size up 2 sizes and be prepared for a wide and "dumpy" waistline as a result...it's the unfortunate result of the cut, I'm afraid.
