Erin and Sara Foster are used to being described as writers, producers, actors, entrepreneurs, maybe influencers -- but “fashion brand founders” is a new one.

“I think it’s a combination of imposter syndrome and of, like, ‘Wait, pinch me, we have a fashion brand,’” said Sara Foster, upon being caught off-guard by her Glossy Podcast introduction.

After a successful collaboration with Joe’s Jeans in 2020, the sisters launched their apparel brand, Favorite Daughter, through Joe’s founder Centric Brands on December 1. They’re now focused on taking it to the next level, starting with reaching shoppers beyond their Instagram follower base (which, combined, tops 1 million).

“Right now, people are buying Favorite Daughter because of us. But we don't want that to continue for the long term,” said Erin Foster. “We want people to find Favorite Daughter and like it because they just like it -- and maybe they know that we're behind it, and maybe they don't.”

After launching with a focus on women’s ready-to-wear and DTC online sales, the founders have been busy with expansion plans. They’re currently considering brand collaborations in the footwear and jewelry categories, as well as eying the kids’ clothing space and scouting locations for potential stores.

“We know that we have to find ways to separate ourselves in this totally oversaturated market,” said Sara Foster.

Along with strategies for differentiating, the founders also discussed their “privileged” path in fashion and the lessons they’ve learned from fellow female leaders.
