The Simple Folk began in 2018, making clothing for its founders' own children after struggling to find soft, functional pieces made without compromise. The range grew to include womenswear with easy layers and relaxed silhouettes. The brand uses natural fibres, has removed elastane from most of its range, and documents its knitwear cotton from farm through gin, spin, dye and stitch. Knitwear dyes meet ZDHC standards. In 2025 the brand joined Inside Out, a collective of brands led by Suzy Amis Cameron.
