Thanks so much for the tip on the ON corduroy tunic:

I went out and got one today on sale ($15 - 15% off with coupon) - it was the last one in my size! It's actually much longer on me - almost knee length so I suspect that the petite would fit more of a tunic length. I ended up with the same color as you since they didn't have much of a selection. I will post pics soon once I get a chance to play around with it a bit.
