Ok, OP here. The first woman I asked did not even attempt to size me, just sent me to the 'plus' section. When I got to the plus section, she did not size me either, but looked me up and down and asked me what size t-shirt I wear. I usually wear a medium when I wear stretchy tees, large when I don't. She told me they will not have anything in my size in white ever. I should not go other places, either, I should just call and that way I don't have to be disappointed everywhere I go. Thank you guys for your words of encouragement, but I think I'm just going to not get a dress.
