A twinset, twin set or sweater-set is a matching set of a cardigan and a (usually) short-sleeved jumper or pullover. The twinset first appeared in the 1940s, but is now considered a classic wardrobe staple.^{[citation needed]}

The classic twinset is knitted in wool or cashmere, though modern interpretations can be knit from synthetics such as acrylic. The under-sweater is usually worn tight-fitting, with the cardigan unbuttoned to reveal accompanying jewelry, most typically a string of pearls.

Twinsets have been associated most closely with women's work wardrobes during the 1950s and 1960s, particularly in secretarial work or teaching, but were occasionally viewed as too casual for more conservative workplaces where dress suits were preferred. However, their popularity was largely driven by Hollywood stars such as Grace Kelly, Marilyn Monroe, and Audrey Hepburn who were frequently seen wearing them on and off the set.

The twinset is often chosen by costume directors and designers in the modern film industry to portray a character's conservatism or frumpiness. For example, Joan Cusack in the 2004 film School of Rock wears a grey twinset with pearls, intended to indicate how conservative she is. On the other hand, interest in the twinset returned thanks in part to the pink set worn by Elizabeth Hurley in the 1997 film Austin Powers: International Man of Mystery.
