In the beginning of the scene where Rory is wearing a nice polka-dot dress and white hat, she walks down the stairs wearing white sandals with a small brown heel. Her and Noah go into the living room to discuss the B&B's new logo with her sister. In this shot, her shoes are much taller heels and completely white. Afterward, her and Noah run outside to the falls where her heels go back to the white sandals with the small brown heel.
When Noah runs Rory's credit card on the old credit card machine, he gives her both copies. How is he going to get paid? That type of machine the proprietor had to turn the hard copy into the credit card company to get paid.
Rory is wearing her purse on her arm as she walks down the aisle. No one does this. During the ceremony, there is no purse strap, but after that when she is talking to her sister, the purse is back on.
