That looks like a dress I saw on The List w/Debbie D the other day. I had just tuned in, so it was the last item in her show I think. It has a waist tie that the models tied in back, making it look like a wrap dress, or you could tie it in front like Debbie did, or she also untied it and let the ties hand down making it look like it had a topper, or maybe it was a matching topper. Sorry I can't help more.
@lovethgedress I couldn't find it. Maybe the photo, if that is the dress you are looking for, helps, and you or someone else can find it. I wish QVC would stop including in the sets fashions that it is not featuring. I can tell you that I tried on and off for months to find a top hanging on a set and never saw it.
