It's summer. You're on the beach, by the pool or in the garden — it might be time to get your swimwear out! But if you're talking about swimwear in English, there's a small problem: there are many different words for it. "Swimwear" can be used for anything you put on to go in the water, whether you're male or female, so it's always a safe choice of word. You might also hear "swimmers" used by people from Australia. This means the same thing, and it's always used with the "s" on the end. In Australia, New Zealand and Ireland, swimwear will also often be called "togs." And Australians also say "bathers." It's short for "bathing suit," which in British English usually refers to women's one-piece swimwear, but in American English can be anything you wear to swim in. Anything you swim in can also be called a "swimsuit." "One-piece" can be used on its own to refer to women's swimwear that's made from one piece of material, as opposed to a two-piece swimsuit like a bikini. In the UK, the term "swimming costume" also tends to be used to talk about female swimwear. Some British and Australian English speakers might shorten this to "cozzie" — sometimes spelled "cossie," but said the same. In the US or Britain, men going to the beach shouldn't forget their "swimming trunks." These are the casual shorts people often wear. You'll hear these called "board shorts" or "boardies" in Australia. Men who are going for a serious swim might choose "Speedos." Speedo is the name of a swimwear company, but the word is now used across the world for the tight briefs men might wear when they want to swim very fast.
