Men's letter-size body references use adidas tops and adidas bottoms. Numbered jeans and kids' body references use Levi's size guide. These are named-brand comparisons, not a universal sizing standard or measured FNF inventory.
Size labels follow the FNF ranges shown. XXL and XXXL correspond to source 2XL and 3XL. Kids' 2 and 3 use the source's 2T and 3T references; 7 uses 6X/7. This is a reference mapping, not a guarantee that the labels fit identically.
Fit pictures are illustrations, not product measurements. A photo does not establish an exact shirt length or leg opening. Availability and fit details depend on the individual item.
References checked 7 October 2026. Exact garment dimensions and lengths are intentionally not guessed.
