Year of Ours to Old Navy leggings size
The short answer
Year of Ours Extra Small is Old Navy XS by the two brands' own charts. 6 of 6 Year of Ours sizes land on a different label at Old Navy.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 1 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.
