In my street clothes, I wear a size 10-12. I am actually really happy with that size for right now because I lost 75 lbs to get there

But the problem is, this is not the average sample size for wedding gowns. As I did some preliminary browsing, I found many dresses I liked but they were size 6 or 8 (and I know bridal even runs small). Sure, they can order in a bigger size, but how do you get an accurate idea of whether or not it will even look good on you if it is that much too small for you? I don't want to spend that much money on a dress I love on the hanger but not on me. Or am I relegated to only choosing from dresses larger than my current size because at least I can try them on?
