The expression one-size-fits-all comes from the garment industry. By the 1970s, many retailers carried oversized or billowing items; they were designed to fit a range of sizes. By the 1990s, companies experienced a backlash from people who did not fall within the range of sizes for a one-size-fits-all item.

Most ready-to-wear designers began using the designation: one-size-fits-most. It was just about this time when the popularity of the idiom one-size-fits-all really took off.

How Did the Idiom Evolve Over Time?

Over time, the expression has expanded beyond the fashion industry and is now used more broadly to describe any product, solution, or approach claiming to be universally applicable or suitable for various situations or individuals. It has become a metaphor for a one-size solution that supposedly fits everyone, regardless of differences in preferences, needs, or circumstances.
