Gyaru is a type of fashion and way of looking that started in Japan a long time ago. It's like playing dress-up but for grown-ups. People who like the gyaru style like to wear clothes that are really bright, colorful, and sometimes fancy. They also like to wear their makeup in a special way, with big eyes and sometimes fake eyelashes or sparkles. They make their hair look a certain way, too, and sometimes wear wigs or hair extensions to make it extra long or curly. It's kind of like putting on a costume every day, but it makes them feel confident and happy!
