For my 2nd marriage I weighed right at 200 lbs when I got married, and wore between a size 18-20.
I found many lovely gowns, but none that I just truly
loved that I tried on. But there were 2 that I saw on the internet that I really liked - one I loved the body and train of, the other I loved the top and sleeves of (and my arms are very large - so extremely hard to fit in "normal" clothes). So I took the 2 pictures to a local seamstress and asked if she could make me a wedding dress. And she did! She also made my daughter's flower girl dress to match.
And by having this very personal wedding dress done - it was completely my size, my style, and flattered ME - not some model in a catalogue.
