I had my first dress fitting a few days ago and ended up passing out and hitting the floor. I think it was a combo of not eating enough, not staying hydrated, standing for a while, and being way over heated. Is there something I can do besides eat, drink water, sit, and stand over a fan to stay cool on the day of? I know, logically, that I should be fine if I do these things, but part of me is so paranoid that I'm going to pass out at our wedding!
