June Thirtieth was founded by Jacqueline and Danielle, longtime friends who built a fragrance house named after a date carrying deep personal meaning. For Jacqueline, the project began as a tribute to a mother and first creative influence, created in the wake of that loss. For Danielle, it followed more than fifteen years inside the fashion industry. Working out of Brooklyn, the two co-founders set out to bottle scent as something closer to memory than perfume.

The current collection holds three scents — OG, Vanilla's Muse, and Serene Santal — each built on opposition: tenderness against intensity, polish against grounding, the timeless against the current. Every formula is vegan, with green-chemistry content reaching as high as 99.5 percent and ingredient sourcing that includes a certified, woman-owned farm in the Balkans and a certified sandalwood supplier in New Caledonia.
