When In Doubt - Size Up:
RuffleButts & RuggedButts designers have done their best to make their products run/fit as true-to-size as possible. With this said, they absolutely realize little ones come in all shapes and sizes, as well as grow at different rates. If in doubt as to a size, sizing up is recommended.
Rear Ruffles:
Many RuffleButt designs feature the signature rear ruffles for adding cuteness and flair. Please note that NOT ALL sizes were designed/created with these ruffles. Items without rear ruffles on some sizes are denoted both in the Product Details / bullet points section on each item's page, as well as in an image showing the product without these rear ruffles. These are omitted to give products in larger sizes a more mature look.
Toddler Bloomers:
The 2T/3T RuffleButt Bloomer is sized to accommodate toddlers as they grow up and out of their diapers and can be worn as a diaper or panty cover. RuffleButt finds that many children are able to wear this size beyond age 2, and often into age 3. The knit version will accommodate growth even better, as this fabric is designed to stretch.
