Edna Mode looks very similar to the actress Linda Hunt: they both are quite short, have similar facial features and the same hairstyle. However, the character’s personality would suggest that more likely costume designer Edith Head was the inspiration for Edna.

And the appearance is not that far off either. They both have a similar bob cut and the signature round glasses. Among Head’s famous quotes are "Some people need sequins, others don't" and "Your dresses should be tight enough to show you're a woman and loose enough to show you're a lady” which wouldn’t sound too uncharacteristic.

And although The Incredibles director Brad Bird hasn't confirmed the fact, many say that Edith Head is the best guess.
