Per their aesthetic, the '70s-inspired pieces include a jumpsuit, bodysuit and plunging necklines.

Leave it to Alana, Este and Danielle Haim to breathe some life into staid New Year’s Eve dressing. The talented musical sisters with distinctive taste have partnered with L.A.'s sustainably made cool-girl staple Reformation on a 10-piece collection, debuting Dec. 5 online ( and in stores.

The girls worked for months to co-design the NYE collection, titled Ref x Haim, alongside Reformation CEO and founder Yael Aflalo. As longtime fans of the brand — they tell Pret-a-Reporter their "closets are filled with their pieces" — Haim says being approached about the collaboration "is literally a dream come true. It’s awesome to celebrate their mission of sustainability and work together with like-minded women by doing a collaboration and putting twists on some Ref classics."

When it comes to their inspiration, the mood board featured plenty of icons: Cher, Bianca Jagger and Diana Ross, for example. It seems safe to assume '70s tunes were on heavy rotation during the design process, too. Their halter jumpsuit, long sleeve bodysuit, asymmetrical necklines, dresses and moto jacket in a palette of black (chiffon, patent leather, velvet) with silky gold and red is totally evocative of that era.

Each sister had her say and input, evidenced by their favorite pieces from the line ($128-$398). Says singer/guitarist Danielle, "The Houston top ($128) is my favorite. I struggle with tops that are really low cut because one wrong move can show a little too much, but we designed this top with a tie you can tighten that prevents any nip slips!"

As for Este, the bassist, her standout style is the Balboa dress ($218), which they designed as a nod to '90s minimalism, "but still super fun and sexy," she says. "I love that it’s one-shoulder, but the best part is the detail on the back!" And Alana, the youngest, pushed for the dramatic Berry Jumpsuit with plunging neckline. Her reason? "I've always dreamed of owning a Charlie’s Angels jumpsuit ($128) — it makes me feel feminine but badass at the same time.' Leave it to Haim to walk that line perfectly.
