Spanx to Beyond Yoga leggings size
The short answer
Spanx 1X is Beyond Yoga XXL by the two brands' own charts. 3 of 8 Spanx sizes land on a different label at Beyond Yoga.
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.
