Target (A New Day) to Threads tights size

The short answer

Target (A New Day) L/XL is Threads D by the two brands' own charts.

Both brands publish height and weight ranges. A row shows the size that covers most of the source size's range; where two sizes share it, both are listed.

Every Target (A New Day) size read across to Threads. Letter sizes on the left, Brand's own on the right.
