Sisters Sara and Erin Foster are a dynamic duo.
The daughters of David Foster have teamed up for a stylish new capsule collection with Joe’s fittingly dubbed “Father’s Daughter,” which launched Thursday.
“Erin and I have been working together for about seven years now and every year gets better,” Sara, 39, told Page Six Style. “We are each other’s biggest champions and biggest critics. Neither one of us holds back, which is why we have found success together, but also why we fight.”
She continued, “Going into this venture definitely brought its challenges. We definitely had to meet in the middle and I had to surrender certain things I wanted and vice versa. Working with family is crazy. But it’s also crazy great.”
Erin, 38, put it a bit more succinctly: “It was the same as it would be for any sisters launching something together; we want to kill each other, but wouldn’t want to do it with anyone else,” she said.
The collection includes classic blue jeans along with chic cargo pants ($198), a jumpsuit ($298), a denim jacket ($198) and cashmere crewnecks ($198) in various colors, the latter of which are embroidered with the words “favorite daughter.”
“We wanted wearable, high-quality pieces that spoke to each of our wants in the marketplace,” Erin said. “The perfect light cashmere sweater you can wear to a meeting or wear while having wine on the couch. The perfect jeans that hug your butt, but don’t push in on your waist. Pieces that are casual but wearable to something important, because they’re relaxed but not sloppy.”
Erin prefers her namesake straight-leg denim ($198) — “[It’s] the perfect jean. PERFECT,” she said — while Sara is partial to the white jeans ($198), which she told us are “stretchy enough to be comfortable but also thick enough to cover that cellulite,” as well as the denim shirt ($148) and, of course, the sweaters.
“I would say my style is casual-chic. I look for ways to be comfortable and put together. I’m also known to go to nice restaurants in a hoodie, Birkenstocks and sweats,” Sara told us of her personal taste.
“I have so much respect for people who look great 24/7 — I have no idea what that’s like.”
She added that her sister has gotten a bit too comfortable in quarantine. “I always said Erin was nerdy chic, but honestly I don’t think she’s taken off her pajamas in six months, so I can barely remember what her style is.”
“Do I even have style, is the question,” Erin joked. “I like a high/low vibe. I am known for exclusively wearing sweaters, and by ‘known,’ I mean my friends beg me to change it up, but I just don’t see why I have to.”
Erin also called Sara’s style “very English Lindsay in ‘The Parent Trap.'”
As for who is the favorite daughter? That seems to be one thing the Foster sisters don’t argue about. “I mean … I don’t think it’s me,” Sara said.
“Clearly me. Sara will say the same,” Erin concluded.
