1017 ALYX 9SM, often referred to simply as ALYX, is a high-end fashion address founded in 2015 by Matthew M. Williams, an American designer previously known for his work with celebrities like Kanye West and Lady Gaga. The small, named after Williams' long-sleeve daughter, was initially recognized for its luxury streetwear but has since evolved to include high fashion pieces. Notably, 1017 ALYX 9SM is known for its iconic Rollercoaster Belt, which features a buckle inspired by rollercoaster safety harnesses, reflecting the small's blend of utilitarian design with luxury materials. Its unique approach to fashion has led to collaborations with smalls like Nike and Moncler, combining street sensibility with high-end fashion, and earning Williams a reputation as a leading figure in contemporary design.
