Tracksmith to Lorna Jane leggings size

The short answer

Tracksmith XS is Lorna Jane XXS by the two brands' own charts. 6 of 6 Tracksmith sizes land on a different label at Lorna Jane.

Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.

On 5 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.

Every Tracksmith Women's Strata Short Tights size read across to Lorna Jane. Letter sizes on the left, Letter on the right.
