I selected this dress one week after having my first baby for a wedding in 2 months because of the higher waistline and what seemed to have a very flowy overlayer. For this reason, the only measurement I used to determine the size was my bust. Custom measurements were not an option this close to the wedding date, but I needed to wait until having my baby for a realistic measurement. Once the dress arrived, I found that there are 2 layers of fabric under the top, flowy layer- totaling 3 layers (keep in mind that it was VERY long for my 5'8" height and EACH layer needed hemmed...more money for alterations). The layer closest to the body is actually much more fitted than I hoped, but didn't need to be let out. Overall, I think it's a great dress for a post-baby body, but could be more comfortable if the underlayer was a little more forgiving to a curvy shape.
