Baby Clothing Size Guide (0–24 Months)

This chart is suitable for both baby girls and boys. For smocked outfits, we recommend sizing up if the child is between weight ranges to allow for the classic "room to grow" look.

Toddler Clothing Size Guide (2T–5T)

How to Measure

• Height: Measure from the top of the head to the floor while the child is standing straight.

• Weight: Use the child's most recent weight for the most accurate fit.

• Chest: For smocked dresses and tops, measure around the fullest part of the chest, keeping the tape comfortably snug but not tight.

Important Fit Tips

Natural Fabrics & Stretch

Our garments are made from breathable, high-quality fabrics:

Cotton: cotton, pique cotton

Cotton Blend: cotton-polyester

Linen: linen, linen blend (linen-cotton)

These fabrics feel soft and natural, but they offer minimal stretch. If your child is at the top end of a weight or height range, we recommend sizing up for extra comfort and longer wear.

24 Months vs. 2T: What is the difference?

While the age range is similar, the fit is different:

• 24 Months: Designed with extra room in the seat to accommodate diapers. It is generally shorter and rounder.33

• 2T: Designed for toddlers who are potty training or wearing thinner pull-ups. It features a slimmer fit in the seat and a taller silhouette.

Smocking & Embroidery

For our smocked dresses and bubbles, the chest area is gathered. To get the best fit, measure around the fullest part of the child's chest. The garment should fit securely but allow enough room for the child to breathe and move easily.
