I think the Kate could be quite nice and flattering and, if it's good quality, not too expensive as you'd probaaly get a lot of use from it.
Unfortunately, not all Boden stuff is good quality in my experience - some is, some isn't. If I thought it would suit my figure (which sadly I don't) I'd certainly order the Kate to see what it's like, using a code for 15% off and free p and p - see separate thread.
