What are the English-speaking countries? What is the most famous culture or fashion in these countries?

There are many English-speaking countries, some of which are native speakers of English, such as Britain, America, Australia and continental Europe. Some countries have been colonized by European countries before, and they also speak English, and even the official language is English, such as India and Singapore. But Indian English is not very easy to understand and not very standard. Basically, on the earth, except Asia, China, Koreans, Japanese, Vietnamese, Burmese, Russians are Russians, Europe and Africa are basically English, North America is English, and South America is Spanish.

As for the culture or fashion of these countries, there are too many, depending on the specific situation. If you are interested in a country, you can focus on understanding cultural customs and so on. I wish you progress in your study. If the answer is satisfactory, please adopt it. Thank you.
