Kazala, thank you so much!
Have you tried using the locator on the Sottero Midgley website to see if maybe there were some stores that sell them that you might not have known about. Can you at least order the dress even if they don't have a sample?
Also, I see a lot of them for sale by brides on the forums and such and trust me, if I could have found one online in my size I totally would have bought it for half price.
The sample size was too small for me in the store so to get an idea of how it would fit me I just tried on a different S&M that was a similar shape and it really did help me picture it.
I really hope you get the dress you want!!!
