7 For All Mankind to Old Navy jeans size
The short answer
7 For All Mankind 24 is Old Navy 00 by the two brands' own charts.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 4 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.
