Reformation to 7 For All Mankind jeans size
The short answer
Reformation 29 is 7 For All Mankind 30 by the two brands' own charts. 3 of 9 Reformation sizes land on a different label at 7 For All Mankind.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 2 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.
