Humanity Code × Longevity Muse: “Sunset Serenity,” made for real life

Some collabs feel like a deep breath. Humanity Code × Longevity Muse is one of them—two women who built brands out of lived experience and met in the middle: comfort you can trust, beauty you can feel, clothes that actually keep up with a day. And we are telling you this because we actually tried it and exercised in it. No bs here.

Longevity Muse is Caitlyn Princen’s way of turning healing into a practice you can hold—soft rituals, honest conversations, a gentler pace that still gets you where you’re going. Humanity Code is Yara El Gabry’s answer to sensitive skin and long days—pieces that are kind to the body and easy on the eye, moving from class to commute to dinner without the costume change.

Together they made Sunset Serenity: an edit you’ll really wear. Think flared trousers with that easy swish, a cropped wrap that loves a plane seat and a café chair equally, sculpting leggings that don’t boss you around, and tops that land somewhere between studio and street. The palette keeps things calm—mocha, cream, navy, baby blue, black—so getting dressed feels like choosing a mood of the day.

What we like most is the attitude. Everything sits right on skin, plays nice with what you already own, and holds its shape from morning to night and from pilates to brunch with the gals.

The women behind the capsule

Caitlyn Princen — the why
Longevity Muse began as Caitlyn’s own healing: navigating PCOS, studying health coaching, and slowly building a community around conscious, intentional living. With a multicultural background, she blends Eastern philosophies and Western wellness through a grounded, feminine lens—less “fix yourself,” more “understand yourself.” That’s the energy she brings to this collab: softness with spine, ritual over hype, clothes that support how you actually move through a day.

Yara El Gabry — the how
After 12 years in corporate, Yara walked away to solve a problem she lived with: a skin sensitivity (heat rash) that made most activewear a no-go. She went deep on textiles and construction, then founded Humanity Code to make skin-friendly pieces that “activate the wardrobe”—switching from active to travel to lounge (even maternity) without losing shape or intention. Her brief is practical and empowering: design for multitasking women so they feel strong, beautiful, unstoppable.

The capsule is available at humanitycode.shop and via @humanitycode.shop × @longevity_muse. If your fall mood is ease with intention, this is your uniform.
