Size Guide

Smarty Girl fits true to size.

The fit is similar to Target's Cat & Jack leggings. But you want to be sure. And wrestling a toddler with a tape measure? Sounds...not fun.  

Rather than a chart based on your child's size, it's easiest to measure a pair of her favorite leggings then compare with unwashed Smarty Girl leggings laying flat:

The above chart is for Smarty Girl's collection of astronaut, robot, narwhal and vehicle leggings. 

Sloth sizes 12-18m through XS 4/5 fit slim in the waist and long in the leg; consider sizing up.

When in doubt or between sizes, buy the larger pair. Better to be a bit baggy at first and fit more snug as kids grow.

Leggings may shrink if washed in warm and machine dried. I recommend washing in cold and laying flat to dry.
