In the following two excerpts say why, in each case, a person or people have "put on" a regional accent

The article about the USA demonstrates that, at times, it is possible that people can adapt their natural accents or dialects to either avoid or intentionally adhere to "bundles of properties" or stereotypes. The southern accent in the USA is often seen, when adopted by an American who lives in the North, to be drawing upon preconceived ideas of condescension or trivialization. Leading to a perception of the Southern Americans as "backward but friendly, racist but polite, obsessed with the past and unenamored of the finer points of education."

The second article demonstrates a situation in which Standard English isn't seen to be the most suitable vocal style for a particular profession. The use of the word "upgraded" in terms of the accent of the DJ John Peel shows how some accents are seen to be more suitable than others. This change may have been made specifically to avoid the middle-to-upper-class connotations associated with RP, making the music that John Peel was playing more attractive to a much younger, wider audience across the country.
