In the final scene of the "big night" dinner the wine bottles across the table and in the kitchen with Secondo all have the trademark pink DOCG label on the bottle stem. The DOCG pink label was released in Italy only in the 1990s; the movie is set in the 1950s.
When Ann arrives at the restaurant and is standing at the bar, she is wearing black heels. Then, as she walks over to look at the paintings with Primo, she is wearing flat white shoes. When she later dances with Primo, she is wearing black heels again.
