Size zero Size zero Size zero or size 0 is a women's clothing size in the US catalog sizes system. Size 0 and 00 were invented due to the changing of clothing sizes over time (referred to as vanity sizing or size inflation), which has caused the adoption of lower numbers. For example, a 2011 size 0 is equivalent to a 2001 size 2, and is larger than a 1970 size 6 or 1958 size 8. Modern size 0 clothing, depending on brand and style, fits measurements of chest-stomach-hips from 30-22-32 inches (76-56-81 cm) to 36-28-36 inches (90-71½-90 cm). Size 00 can
Size–weight illusion one, causing it to be perceived as lighter. This hypothesis was disproved by an experiment in which two objects of the same mass, same cross section, but different height were placed on observers' supported hands, and produced a passive size–weight illusion. Recent studies have also shown that the lifting force quickly adapts to the true mass of the objects, but the size–weight illusion remains. The illusion therefore cannot be explained by the manner of lifting, and must be due to some perceptual rescaling based on prior expectations. The rescaling has been described as sub-optimal (anti-Bayesian), in that the central nervous
