The earliest swimsuits covered most of the body and were called "bathing costumes." They were often made of wool, which made them scratchy and very heavy when they got wet. Newer fabrics made it possible to make lighter swimsuits. Over time, swimsuits covered less and less of the body. In 1946, the bikini became popular for women.
Summer holidays don't just mean going to the water. They can also mean going for a hike, a bike ride, or a picnic. What's your favorite way to spend a summer day?
