In April, Earnest Sewn, the premium denim purveyor, is devoting its Back Room space to the patriarchal eyewear company Moscot. The new installment will launch the two brands’ collaborative collection of co-branded Buffalo Horn Moscot Lemtosh frame specs. These one-of-a-kind styles are designed with real glass and colored lenses just as they were 70 years ago. And for bragging rights, each pair will also be numbered for authenticity.
