The Vision Behind 1017 ALYX 9SM
The name carries personal meaning: 1017 marks Matthew Williams' birthday, the seventeenth of October, while 9SM nods to the brand's first studio on Saint Mark's Place in New York. From the outset, the label set out to merge industrial precision with refined, wearable design, and that tension still drives every collection.
