Now that I see this, I don't like it at all.
Isaac did a knit version of this top last year. It was just a This Day Only last week. I ordered it and the top was very ill-fitting and ended up in the donation bag very quickly. It was not one of my better purchases.
On the knit version, the fit was very off in the arm/shoulder/bust areas. It pulled through my upper arms and across the bust darts but was big across the neck and shoulders. It gaped at my neck. So I couldn't go up a size for the arms and bust to fit because the neck and across my shoulders would have been huge.
The seam on the peplum isn't at the natural waist. It cut me right through my abdomen and that wasn't flattering at all plus it just felt off. That seam should have been lowered to hit at the natural waist, not cut you in half.
If one carries weight through the mid-section, I think this would be horrible because that seam is going to cut right through the extra in that area and really emphasize that.
