How does one wear a cascading cardigan? I am an inverted triangle/rectangle shape. I can't get used to the extra volume around my middle and losing the waist definition.

Does the type of open cardigan that are open in front, rounded in back, less volume work okay for the rectangle/triangle body type? The one that comes to mind is a beautiful lavender sweater that I think Inge posted a month or so ago.

I feel like an ice cream cone when I wear big over small...
