Amanda Seyfried's TIFF 2014 Dress Is The Perfect White After Labour Day Look

Now that's how you wear white after Labour Day!

Amanda Seyfried hit up the TIFF 2014 red carpet on Saturday evening for the screening of her movie, "While We're Young" wearing a Valentino ensemble that is perfect for fall (even though it's still technically summer. Sigh).

For the premiere, the 28-year-old "Mean Girls" star sported a stunning frock that paired a white lace top and an embroidered green-and-pink floral skirt that hit her just above the knees.

The actress' hair and beauty look were on-trend too: Amanda styled her tresses into a braided ponytail and highlighted her stunning face with bright pink lips and smouldering eye makeup.

But the blond beauty wasn't the only actress making an impression on the red carpet. Co-stars Naomi Watts and "Girls" star Adam Driver also hit up the premiere, to the delight of all their fans.

Amanda is definitely one of the best-dressed celebs at TIFF 2014 so far!

Amanda wasn't the only celebrity to look stunning at TIFF 2014:
