Use these body measurements as a guide to select the size that's right for you. Our baby one piece is designed for a comfortable feel that allows easy movement and all-day wear. If your baby is at the lower end of a size range, expect a looser fit, in the middle the fit will be relaxed, and at the top end it may feel closer to the body.

How to Measure
  1. Chest
    Wrap the measuring tape around the fullest part of your baby’s chest, keeping it level and comfortably snug under the arms.
  2. Waist Measurement
    Measure around your baby’s natural waistline, typically just above the belly button, keeping the tape level and comfortable.
  3. Hip Measurement
    Measure around the fullest part of your baby’s hips and seat, keeping the tape level all the way around.
  4. Garment Length
    Measure from the highest point of your baby’s shoulder straight down to where you want the one piece to end.

Legendary Comfort™

That soft, all-day feel you never want to take off. Built to hold up for years, but somehow still feels like day one. You’ve worn it enough to know, nothing else in your closet comes close.

Sizing

Our baby one piece is designed for a comfortable fit that allows for easy movement and all-day wear. It is made from a soft cotton blend that may shrink slightly after washing, so we recommend washing cold and tumble drying on low to help maintain the fit. Check the Size Guide for fit tips.
