Continuity mistake: When the fairies are trying the dress on Merryweather, the background behind her differs between shots: the ironworks disappear as well as the design of the carved flowers.
Continuity mistake: Aurora's crown has no jewels, but when she collapses jewels suddenly appear on it.
Continuity mistake: While Maleficent is in her throne room filled with her henchmen in the Forbidden Mountains, she's wearing her large ring on the index finger of her right hand, but in some shots, that ring is either on her left hand or has vanished altogether. (00:16:00)
Continuity mistake: Anytime the eye colors of the fairies are shown, Fauna's are very obviously brown. However, when the fairies are with Aurora after the curse takes place, a close-up of Fauna holding a handkerchief shows her with blue eyes.
Continuity mistake: When Merryweather makes the dress blue a second time, it starts off on a ribbon that wraps itself around the dress waistline. The ribbon doesn't make it onto the completed dress.
Suggested correction: Hardly a mistake, since they're using magic and the dress changes multiple times.
