I don't blame you. Tripping and ripping the hell out of that gorgeous heirloom dress is too great a risk to bother with heels. Besides, if you never wear them and never have? Even if you didn't trip, all you'd be able to think of from probably an hour or two in was how much your legs hurt. Not, I'm sure, what you want the memory of your big day to be. (Mine, granted, is mostly thinking 'Stand up straight, stand up straight, DON'T ASK THE JP TO REPEAT HIMSELF!, stand up straight, sit up straight, DON'T SPILL ANYTHING ON THE DRESS!')
