Schools are introducing 'vanity clothing' in order to combat the expanding waistlines of Aussie kids, with uniform sizing adjusted to be badged as smaller sizes.
This comes as manufacturers are producing outfits as larges as a size 34 for girls and 7XL for boys.
According to a News Corp report, sizes are now typically from 4 through to 16, with 18 onwards labelled as 'small', 'medium' and 'large'. A former size 12 uniform is also being labelled as a size 10.
A comparison with uniforms from 1982 shows that a size 10 today is more than 4cm larger.
The labelling change comes as some manufacturers have reported children crying in the change rooms over their sizing.
More than one in four Australian children is overweight or obese, with representatives from the Australian Medical Association warning vanity sizing stands to undermine the real issue.
