Cosi Tutti has designed and produced workshops for the maison Eres on two occasions: first at Bon Marché for a collaboration with Chloé, then as an introductory seminar about Colorimetry for Eres' worldwide store managers. The workshop offered the opportunity to discover this technique - also known as Armocromy - dedicated to the study of colour as a tool to facilitate and accompany one's styling choices. The event’s content was developed by Cosi Tutti, who also scouted the expert in charge.
