Size Guide – Only Little Once Designs

Kids' sizing can vary, so we recommend measuring your child and comparing to the chart below before ordering. When in between sizes, we suggest sizing up for room to grow.

Note: These are placeholder measurements. Please confirm with your supplier before publishing.

How to Measure

• Height: Measure from the top of the head to the floor (without shoes).
• Weight: Use your child's current weight.
• Chest: Measure around the fullest part of the chest, keeping the tape level.
• Waist: Measure around the natural waistline.

Fit Notes

• Maxi & Twirl Dresses: These styles run long — if your child is between sizes, size down.
• Athletic & Fitted Styles: These tend to run small — when in doubt, size up.
• Layered or Tulle Styles: True to size.
