Rachel Bilson‘s makeup-free swimsuit moment shows she’s truly in her confident, hot girl summer era!

On Aug 22, The OC alum shared a series of photos on her Instagram of how her summer 2025 has been going. She shared the photos with the caption reading, “Some Summer….”

In the photos, we see her in a super-chic LBD, along with pics of her in London with her daughter Briar Rose and her pals, the iconic Olivia Rodrigo concert, of her lounging, and the picturesque scenery. However, we gotta talk about slide seven!

In slide seven, we see a bare-faced Bilson looking so stunning in a pink and white striped bikini from Solid & Striped (yes, the same brand used on The Summer I Turned Pretty). We see her bare skin, freckles and all, as she took this stunning selfie, and we’re obsessed (plus, we’re also obsessed with the street gold necklace with her daughter’s name on it)!

Whether it be an on-set moment, or a candid moment like this, Bilson always learns something from it all, making her a wise, confident icon. And in a previous interview with SheKnows, Bilson talked about what she learned as she’s grown older. She said, “You really learn to appreciate the moments you have to yourself, and the things that you do that you’re proud of — especially having a daughter — are so important. So yeah, for me, it’s huge.”
