Denim is a word name taken from the sturdy blue cotton fabric, whose name comes from the French serge de Nîmes, "cloth from Nîmes", the southern French city where it was woven. It belongs to the recent American taste for cool, casual word names like Maverick and Legend. Denim entered the US top 1000 for the first time in 2025, at number 880, after a decade hovering between numbers 1100 and 1600.
