Language
There is no official language of the United States, according to the U.S. government. While almost every language in the world is spoken in the United States, Spanish, Chinese, French and German are among the most frequently spoken non-English languages. Ninety percent of the U.S. population speaks and understands at least some English, and most official business is conducted in English.
Religion
Nearly every known religion is practiced in the United States, which was founded on the basis of religious freedom. About 83 percent of Americans identify themselves as Christians, according to an ABC poll, while 13 percent replied that they had no religion at all. Another poll in 2012 reported similar findings. It also found that Judaism is the second most-identified religious affiliation, at about 1.7 percent of the population. Only 0.6 percent of respondents identified as Muslim.
American style
Clothing styles vary by social status, region, occupation and climate. Jeans, sneakers, baseball caps, cowboy hats and boots are some items of clothing that are closely associated with Americans. Ralph Lauren, Calvin Klein, Michael Kors and Victoria Secret are some well-known American brands.
American fashion is widely influenced by celebrities and the media, and fashion sales equal around $200 billion per year, according to a paper published by Harvard University.
These are 3 of the many things that represent our American culture. I hope this helps.
