Plus sized problem....

I am a plus sized bride and I am having the worst time finding white pantyhose. I've surfed the net and visited several stores in my area to no avail.... I've found plenty of places that sell nude and ivory stockings... but I really need white! Thigh highs are out of the question, because my hips and thighs are where I carry the most of my weight - and I want to be comfortable that day. The wedding is 15 days from now... Anyone else having the same problem? Any suggestions as to where else I may try looking? I'm really getting a plus sized headache over this
