If you wear a sequined belt to school on Monday, and by Friday there are dozens of kids wearing sequined belts, you're a trend-setter. In other words, you've started a trend!

When it comes to trends — in fashion or in brilliant ideas — a trend-setter leads the way. Celebrities are often trend-setters, inspiring others to follow their lead, whether in clothing brands, diets, or travel destinations. Innovators, like Marie Curie (the first woman to win a Nobel Prize) and Sandra Day O'Connor (the first woman to serve on the Supreme Court), are also trend-setters.
