Size Guide for Rugrats
Being a big kid means that getting the right size matters!
Underwear sizes fluctuate across countries, please check your waist size below to ensure you get the proper fit.
The easiest way to find the right size is to take a pair of underwear you already own that fits well, lay it flat on a surface, and measure the waistband from one side to the other. Use that measurement to match the garment's 'half waist' size (see Figure A).
