Fit Tips
- A size 18-24M (XL) in Infants is also a size 2T in Toddlers. The difference is that an Infant size garment will likely snap at the crotch.
- A size 4T and a size 4 are usually close in dimensions. The difference is the selection of styles in each.
- Generally, boys grow faster in their arms and legs before they start to gain weight (or "fill-out"). For this reason, measure your child's inseam and check the garment's measurement before selecting your child's size.
- After a child outgrows a size 16 in Girl's or 18 / 20 in Boy's, the pre-teen or teen will move to Women's or Men's apparel.
