Haim's Style Evolution Is A Study In '70s California Cool Girl

Staying true to their signature laid-back 70s style, they kept it casual in jeans and a tee, or a white dress with stockings.

The sisters coordinated their matching printed ensembles with different takes on the motorcycle jacket.

Mastering the casual-chic aesthetic, Danielle wore a slouchy pearl-white blazer, Este went for a long black buttoned cape while Alana rocked a mini red dress.

Once again, Alana and Danielle matched with their head-to-toe black looks. Este chose to stand out with a printed white dress paired with ankle boots.

Channeling their California roots again, Este wore a patterned mini dress; Alana went for a loose blouse with a skirt, while Danielle paired her printed trousers with a crocheted top.

For their first Met Gala appearance, the trio abandoned their casual style for identical sheer evening gowns by Rodarte.

The sisters attended a philanthropic gala in perhaps their most pink ensemble yet.

It's no surprise that Dior dressed the sister trio in head-to-toe looks, as Haim was the performer for Guggenheim International Gala's pre-party, hosted by the French luxury brand.

The sisters wore signature Chanel tweed to the 2018 Chanel party, complete with yellow and pink purses.

The sisters matched their leather Givenchy attires, with Danielle in burgundy, Estee in blue, and Alana in all black.

As front row guests for the Valentino Spring 2020 runway show, the Haim sisters wore same-but-different outfits in a matching print.

Ending on a fashionable note, Danielle wore a see-through long shirt dress over a mini black skirt and bralette. Este sported a long mod white gown, while Alana wore an evening gown with a high slit.

At the 2021 Grammys, the trio wore matching custom Prada looks in a periwinkle blue.
