Meaning:
“BM” is short for the brand name “Brandy Melville,” and in addition to the more familiar meaning “wind,” “风”also means “style.” Thanks to reality TV personality Kylie Jenner who wears this brand on many occasions, Brandy Melville has become popular in many countries, especially in the United States. With teen girls as its primary market, the brand produces clothes in two sizes — S and XS — for very slim girls, and its signature pieces are crop tops, skinny jeans, shorts and miniskirts. The colors and patterns adopted are often light shades like pale blue, white, light gray or checked. To sum up, the term “BM-style” describes a clothing style popular among teen girls and young women that features simple but figure-flattering pieces in small sizes.
