Two cardigan options form the Nonnative world which are not only baseline, but just about what you need from a classic, no-frills garment (sans the simple safety pin closure). “A chunky knit worker’s cardigan from cult Japanese label Nonnative. This piece is detailed with a thick rib shawl collar, thick rib cuffs and hem and a kilt pin fastening. Made in Japan.” Oki-ni has them.
