Use their size chart

I am sorry, go to any store like Macy, s JC Penney, Dressbarn. Where you can try it and not risk it. Their sizes are smaller.
But, not all dresses fit the same! Totally don't risk it! My true humble Opinion!

You just have to follow the instructions given by in the page to take the right measures. I advice you to take the exact ones, not a single inch more or less. We ordered three dresses and they were perfect, but another person ordered a fourth one adding a little bit and it was that "little big" bigger than it should have.

My daughter is also plus size & 4'8", we measured exactly the way JJ's asked us to and the dress was probably 2-3 in too small around the waist. I would not recommend ordering from them, I eventually got my money back but what a pain it was. I ordered both of the dresses I needed from amazon, they had free returns. Both dresses fit great from them and they were not "custom made".
