Old hat is an informal idiom used to describe something that is outdated, old-fashioned, unoriginal, or so familiar and routine that it is no longer interesting, novel, or exciting.
Also: Old-hat (as an adjective), as old as my hat
Two Nuances of “Old Hat” in Modern Speech
The idiom is primarily used in two distinct ways depending on context:
- 1. Outdated or Obsolete: Ideas, technologies, fashion, or slang that have fallen out of style (“Floppy disks and dial-up modems are totally old hat.”).
- 2. Second Nature or Overly Familiar: A skill, task, or procedure that has been performed so many times that it requires no special effort or thought (“Driving a stick shift was terrifying at first, but now it’s old hat to me.”).
Origin & History
The modern figurative expression developed in late 19th-century Britain from the rapid turnover of Victorian headwear fashion:
Victorian Hat Fashion
In the 1800s, hats were mandatory public attire and immediate indicators of social standing and respectable manners. High-quality beaver felt and silk top hats were built to last for decades without deteriorating. However, hat silhouettes, crown heights, and brim widths changed rapidly with fashion trends. A hat would become laughably obsolete and “old hat” long before the fabric actually wore out.
The Shift to “Stale News” (Late 1800s–Early 1900s)
By the 1880s and 1890s, English writers began applying the visual metaphor of an out-of-style hat to worn-out arguments, stale gossip, and familiar routines. Calling an idea “old hat” suggested it was something everyone had already seen and moved past.
The 18th-Century Vulgar Slang Coincidence
Etymologists often note that in the 1700s, old hat was recorded in Francis Grose’s 1785 Classical Dictionary of the Vulgar Tongue as vulgar street slang for female genitalia (due to physical shape). However, this crude 18th-century usage died out completely and is nothing more than an etymological coincidence. The modern idiom arose cleanly from Victorian fashion.
“All Round My Hat” and Victorian Slang
Throughout the 19th century, hats featured prominently in British idioms and music-hall songs, such as the 1830s popular ballad “All Round My Hat” (often used in Cockney slang to mean nonsense or humbug). These popular songs reinforced the hat as the universal symbol of daily routine and public appearance.
