SKIMS to Nike leggings size
The short answer
SKIMS 2X is Nike XXL by the two brands' own charts. 3 of 9 SKIMS sizes land on a different label at Nike.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 3 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.
