The Story
Why it exists.
The beginning
Blue Heat arrived in 2026 as a limited summer edition born from a collaboration between To Summer and French designer Isabel Marant. The fragrance was created in collaboration with Marant, with perfumer David Huang listed among those who shaped the composition. The result brings together To Summer's sensibility for clean, considered scent with Marant's particular brand of warmth. At its center sits Nepal sandalwood, anchoring a composition that orbits around it. Around that central note, sun-warmed florals move with a brightness that recalls the long, saturated afternoons the name suggests.
What makes Blue Heat worth attention is the pairing of hyssop with the creamy depth of Nepalese sandalwood. Hyssop brings a green, slightly medicinal brightness that prevents the florals from going saccharine, and it does so with a kind of herbal confidence that sets the tone for everything that follows. The petitgrain and geranium add a bitter, leafy edge that keeps the white florals from collapsing into sweetness, lending the composition a slightly bitter, cooling counterweight to all that creamy warmth.
The evolution
The first ten minutes are sharp and green, hyssop's herbal bite mixing with lemon zest and the dry snap of pink pepper. Almost like walking through a garden where the sun hasn't quite hit the leaves yet, the top notes arrive cool and bracing, with that particular green sting of crushed herbs hanging in the air. Within thirty minutes the citrus rounds out and the white florals take over: jasmine sambac opens dense and almost indolic, orange blossom brings that orange-flower-water sweetness, and petitgrain keeps everything from getting too pretty with its bitter-green backbone. Geranium sits just underneath, adding a rosy, slightly minty thread that threads through the floral heart and gives it a cool counterpoint. The transition into drydown is gradual but unmistakable.
Cultural impact
Blue Heat marks a collaboration between To Summer and Isabel Marant, a pairing that brings together a Chinese fragrance house and a French fashion house with distinct creative vocabularies. The collaboration moves between registers: Marant's bohemian, sun-soaked visual world meeting To Summer's more restrained, ingredient-led approach to scent. The use of Nepal sandalwood, with its particular creamy warmth, anchors the composition in a material choice that prioritizes texture and depth over volume.
