The Story
Why it exists.
The beginning
Ursula Lengling designed In Between No. 4 around a single proposition: femininity lives in the tension between fragility and sensuality. Neither pole alone is the point. The space between them is. She described the fragrance as "a romantic floral frock", something you wear when you want to be seen differently, or maybe seen at all. Peach and jasmine arrived as the opening act, a gesture of sweetness that would immediately complicate itself. The number four belongs to Lengling's catalog structure, a numbering system that tracks compositions by theme rather than chronology. But this one arrived with an intention: to make the in-between feel like a place worth inhabiting.
Jasmine sambac absolute carries a different weight than its more aristocratic cousins. It's rounder, warmer, with a faintly indolic undertone that the brand leaned into rather than softened. Violet adds its powdery blue character to the heart, threading the floral through with something almost chalky, a texture that recalls pressed flowers in a book rather than petals on a vine. The patchouli does what patchouli does best: it anchors the sweetness before it can float away entirely, and the vanilla follows close behind, wrapping the drydown in a warmth that reads as skin rather than perfume.
The evolution
The peach arrives first, soft, round, almost syrupy in its sweetness. No sharpness here. Mandarin orange adds a brief brightness before both recede, and within fifteen minutes the jasmine sambac has taken the stage. The transition is seamless. You barely notice the handoff because the peach never pushed too hard; it made space. The heart unfolds as powdery violet and warm musk, a combination that reads as intimate rather than loud. This is the phase that lasts. Two to three hours of close, warm florality that behaves less like perfume and more like skin-warmed florals. The drydown shifts into patchouli and vanilla, a woody-balsamic base that grounds the sweetness into something almost edible. Six to eight hours total on most skin. Moderate sillage throughout, present without announcing itself, close without disappearing.
Cultural impact
In Between No. 4 occupies an interesting middle ground in the niche market: floral enough to feel accessible, woody and musky enough to reward someone looking for depth. It's not competing with mainstream florals, and it's not demanding the commitment of heavy oud or leather compositions. The 2015 launch placed it at the early end of the niche boom, before the category became as crowded as it is now.
