How we know

"Buttermilk Agency was tasked with celebrating the launch of Dior's Forever Foundation; a range with 67 unique foundation shades."

Who says so	Buttermilk, the agency. Its founder's interview also records that this was never a pitch: one LVMH contact liked them as people and bought into the Buttermilk vision. Read it
What the agency was asked to do	"Buttermilk Agency was tasked with celebrating the launch of Dior's Forever Foundation; a range with 67 unique foundation shades." (Buttermilk case study)
How the agency was picked	Founder or personal network
How that happened	Prior relationship / personal network, won in a competitive situation against a much larger incumbent-style agency. Buttermilk founder Jamie Ray describes winning Dior as Buttermilk's first client win: the team (then working out of a Krispy Kreme donut shop on the A3 motorway, for the free wifi) 'convinced Dior that we were a better option than an 80-person, global agency' by meeting people in person; one contact 'happened to hold sway within the LVMH group, he liked us as people and bought into the Buttermilk vision.'
How long it took	Not a formal pitch/RFP timeline - described as relationship-driven rather than a structured process. The Dior relationship has lasted roughly 6 years as of the interview's publication (November 14, 2024), which would place the original win around 2018-2019 (the batch's own year field says '2020, referenced again in 2026 coverage', which is consistent within a year or two).
