YOOXYGEN presents an exclusive collaboration with Amber Valletta curating clothing, jewelry and accessories that are both fashionable and socially responsible. We introduce to you Master & Muse.
Master & Muse selection four
Master & Muse is a fashion-forward lifestyle brand that reflects my love of fashion and design, influenced by my personal values. I have discovered artisans, brands and designers who are courageously pushing the envelope in how fashion is designed, sourced, constructed and sold. I am thrilled to offer you these stylish clothes and accessories that are made responsibly and thoughtfully.

The lens I used to vet this selection includes the core values of Master & Muse. Happily, all brands meet two or more of our vetting principles.
Join me and together we will make it fashionable to buy better.
