Sizing Chart

Size Guide

We want you and your littles to feel comfy, cozy, and confident in every piece from The Little Echo. Use the charts below to find your best fit across our full lineup – whether you're dressing a toddler, twinning with your mini, or matching with your pup.

If you're between sizes, we suggest sizing up for a little extra room (especially for fast-growing littles and relaxed hoodie vibes).
