Ribbing for waist shaping

I'm not a shopper but I do venture out occasionally for an afternoon with my friend to wander and see if anything catches our eye. We can hit the expensive stores then and shuffle through the racks looking at garment shapes and style, under the eye of suspicious sales persons, without any thought of buying. On one of our excursions we found a beautiful sweater with the look of a frock coat. It comes in at the upper back above the waist and then fans out again. It was a long sweater which I don't intend to make but when we were looking at this sweater with the centre back panel we thought that pinching it in just above the waist by working straight ribbing might give a similar affect.

This ribbing is just above my waist, although even to me, it doesn't look like it in the photo. I put ribbing in at the sides too but the jury is out on that. It may be coming out. Not sure yet.

Now I have several more inches to work until I'll know if this is going to work. Patience, I hear it's a virtue. I read a quote which if I can remember correctly goes like this: It is not necessary to have Patience it is only necessary to wait. So I'm waiting and knitting.
