She is the younger sister of The Row designers Mary-Kate and Ashley Olsen.

And on Saturday, actress Elizabeth Olsen showcased her own fashion prowess at the Dior Gala Ball, at the National Gallery of Victoria.

The 28-year-old oozed elegance as she led the A-list guests on the red carpet, attending the opening of the House of Dior: Seventy Years of Haute Couture.

Wearing a long skirt with two thigh-high splits, the American beauty showcased her long, trim pins.

She paired the look with a silk deep blue long sleeve shirt, that featured an untied pussy bow collar.

Elizabeth accessorised a white, embellished clutch and kept the jewelry to a minimum with a Cartier Love Bangle and delicate rings.

The Avengers star completed the ensemble with a pair of black, pointy court heels.

She wore her luscious, flowing brunette locks down along her shoulders and parted to the side.

While her makeup was kept simple with a nude pink lip, smoky eye shadow and lashings of mascara.

The Martha Marcy May Marlene star was all smiles as she posed for the cameras in front of the elegant dresses on display. 

Elizabeth recently revealed to ES magazine that red carpet and couture fashion is not her forte.

She said: ‘Sometimes when I’m not in something that I love I cry on the way to the premiere and I’m posing with my shoulders as far back as they go. Then I look at the photos and I’m like, “It did look nice. Why was I crying?”’

The Ingrid Goes West actress also gushed about her fashion designer sisters Mary-Kate and Ashley Olsen.

‘I just think they’re brilliant women,’ she said, adding that she was drawn in by their talk of fashion and business.
