Size zero is the smallest size in America (25 inches around the waist). But now size zero not only represents a clothing size, but also derives a concept, especially in Europe, daily life or film and television, to describe those thin models. So, if you want to be number zero, you must be very, very thin, with only bones left. Some clothing brands even have sizes smaller than size zero, which is called negative zero (waist 23 inches). According to the standard size, women with an average weight of 155 pounds should wear clothes with a size of 16, but they may actually buy clothes with a size of 12, thanks to the appearance of vanity size. Many companies no longer use the standard ASTM "American Social Test and Body Shape". When the size is increased by half an inch at a time, women can find a smaller size, which feels good.

The average American clothing size is 24-68-1012-1416-18, and the standard figure is estimated to be between 2 yards and 6 yards according to everyone's height and weight. For example, a girl with a height of 160 and a weight of 45 kg wears a size 2. No matter what newspapers, magazines and TV textbooks say that girls with a height of 160 want 50 kilograms, it's bullshit. When I weigh 50 kilograms, I look fat, fat and annoying. When I lose 45 kilograms, I look good in anything. I weighed about 50 kilograms at 0/65/kloc. Just wear clothes of size 2 -3.
