If you are not the plus-size person, you may not have used the plus-size clothing. However, if you are an oversized or larger than average person, the term "oversize" is a familiar term and a familiar aspect of your grocery list. The oversize becomes a bigger part of the mainstream.
Plus sizes are clothing with a numerical size of 14 W up to size 26. It is also referred to as X size (1X, 2X, etc.) and has the corresponding numerical sizes. You can even see or hear the oversize clothing, which is commonly referred to as "women's sizes."
In many retail stores, there should be a separate area for oversizes. As the obesity rate in the US increases day by day, oversize becomes a major draw for retailers.
