Rumer Willis and her 1-year-old daughter match with Scout and Tallulah Willis in pink bathing suits

They’re pretty in pink.

Rumer Willis and her sisters Scout and Tallulah joined “the littlest Willis” — Rumer’s 1-year-old daughter, Louetta Isley — for an adorable matching moment on Instagram Wednesday as they coordinated in colorful swimsuits by beachwear designer Hunza G.

The proud mom, 35, shared a carousel of photos featuring her family posing by a luxurious infinity pool and wrote, “On Wednesdays We Wear Pink 🌸 feat. the littlest Willis.”

In the first snap, Rumer wore a $230 bubblegum-hued one-piece by Hunza G and a Jacquie Aiche “mama” necklace ($6,325) as she leaned forward to hold hands with her daughter.

Meanwhile, Louetta, who celebrated her first birthday last week, looked ready for the beach in a tiny pink top and matching bottom featuring an orange tutu skirt ($90).

Rumer’s younger sisters joined in for the matching moment, with Scout, 32, sporting a $215 two-piece in the same pink shade and Tallulah, 30, rocking a tiny Hunza G string bikini ($185).

The eldest Willis sister showed off her new swimsuit in a variety of other pics as she posed with little Louetta, sharing sweet snaps of herself lifting her daughter in the air and feeding her as Tallulah lounged in a chair next to them.

This is the second time the actress has shown off her postpartum body in recent days, with Rumer modeling a brown Hunza G bikini ($230) and a patterned Beachwood baby sarong ($98) on Instagram Monday.

“Leaning in to my mama curves in the jungle 🦜,” she captioned her post, writing that she’s been working on giving her body “room and acceptance” while “it continues to shift and transform after birthing a little human.”

Rumer and her partner, Derek Richard Thomas, welcomed Louetta in April 2023, and last year, she revealed that the baby’s name was a tribute to her father, Bruce Willis.

“me and my dad’s favorite singers are Lou = Louie Armstrong, Etta = Etta James, Isley = Isley Brothers,” she revealed on her Instagram Story in December 2023.

With the Met Gala approaching, here’s hoping for another Willis sister matching moment.
