Since design on the sweater I was thinking about appears to have stalled, I'm looking at another one.  There are a couple pictures of it, here and here.  I'm not sure that this would look good on me–keep in mind that I am rather, well, buxom, and the model is not, also that at least one of the pictures is pretty bad, apparently on purpose.  She does not appear to be wearing the XS size, as hers clearly has waist shaping, but still, she's flatter than I am.
