Plus size refers to clothing that is proportioned specifically for people above the average clothing size. The definition of plus size varies from country to country and according to the industry. In the fashion industry, plus size is identified as sizes 18 and over, or sizes 1X-6X, and extended size as 7X and up. However, some stores start their womens section with size 12 or 14, so when someone reaches that size, they may consider themselves plus size. Plus size clothing is generally considered a womens size 18 and beyond.

It is important to note that the perception of what constitutes plus size has changed over time. For example, in the 1920s, Lane Bryant advertised the first plus-size clothing called “slenderizing” clothes. Today, plus-size clothing plays a major role in retail and brings often-ignored sizes into the fashion fold.

Plus-size clothing is cut differently to flatter the plus-size body, which has a different shape than straight sizes. The bones and muscles of women are essentially the same, but the overall shape can change as they grow. For this reason, plus sizes are cut from an entirely different standard pattern than straight sizes.

In summary, plus size refers to clothing that is proportioned specifically for people above the average clothing size, and the definition varies depending on the industry and country. Plus size clothing is generally considered a womens size 18 and beyond, and it is cut differently to flatter the plus-size body.
