Ader Error is a Seoul-based unisex label run as an anonymous design collective. The name combines "aesthetic" and "drawing" with "error," reflecting an interest in imperfection and the crew's slogan about near-missed things. Collections centre on oversized proportions, layered knitwear, workwear-leaning outerwear, distorted logos and a signature blue, sold alongside bags and accessories. The brand operates concept-driven retail spaces in Seoul and stocks international e-tailers, and has produced collaborations with Zara, Puma and Maison Kitsuné. Design credit stays with the collective rather than a named director.
