Marni still reads as an eccentric, family-run Milanese label, but the Castiglionis sold out and left in 2016. It's now one of OTB Group's six brands, run by Diesel founder Renzo Rosso's son, with no independent labor or environmental disclosures of its own.
The Big Picture
Marni's founding family sold out and left entirely in 2016, and the label has operated for nearly a decade as one of six brands inside Diesel founder Renzo Rosso's OTB Group, now run by his son as CEO. The brand discloses almost nothing about its own labor and environmental practices beyond a leather-tanning certification, scores poorly on independent transparency indexes, and isn't a signatory to the industry's main factory-safety accord. Marni today answers to the Rosso family's conglomerate, not to the eccentric Milanese house that built its name.
