“You know how you’re not supposed to have a favorite kid?” laughs Gucci, as she rummages through her Westman Atelier Train Case—one of three exquisite custom makeup bags, designed and crafted together with Métier, the London-bases luxury goods house. In today’s special Q&A, Gucci sits down for an intimate chat with Melissa Morris, founder of Métier, to discuss the story behind their one-of-a-kind collaboration.

From the collection’s playful nautical wink to the use of sustainable linen and herringbone, woven outside of Lake Como, Italy, every detail was carefully considered by the duo. “It’s been a year and a half of just perfecting the ideas and translating them carefully,” says Melissa. Their goal: “To make sure it was the dream bag realized—which is no small feat.”

Watch the video now for their full chat—from mood board inspiration to practical magic (aka water-resistant everything) —and discover the dream collection!
