After Maggie breaks the heel off a pair of Rose's boots, she changes into leather boots (flat-soled) that she had in the car. She proceeds into the dog kennel. When she comes out later, and the car is missing, she is once again in the high-heeled boots.
When Rose and her boyfriend are making a toast in her apartment we hear a perfect chiming sound. We can clearly see that they're both holding their glasses by the bowl instead of holding them from the stem. Holding a glass this way would never allow a chiming sound.
