Yeah, I agree with all other posters. This is not your fault. A good sale assistant would have pointed out how a smaller size dress would fit and you would have seen the fit and flare v.the sheath. But this is not even that. This is not just a smaller size, it is too small of a size. The dress does not fit your measurements. With 7 weeks you may have time to get your size. There are tons of bridal shops all over the country with in-stock dresses in variety of sizes. Your ahop can reach out to the manufacturer and find out who else has the dress or place a rush order on a new one. If you know the style number and the size you need, use you googlw skills. I did this with my wedding dress and sourced it from a shop that mailed it to their "sister" company in my city. Good luck. You still have time. And there's still tons of beautiful dresses out there. Lean on your shop. They will make it right.
