At SunnyPetal, every gown is made-to-measure—at no extra cost. To ensure a perfect fit for your little one, simply follow this easy guide to take accurate measurements at home.
Step 1: What You’ll Need
- A soft measuring tape (or a ribbon + ruler)
- Paper and pen to record measurements
- A helper (parent or family member)
Tip: Have your child wear lightweight clothing or undergarments—no bulky layers!
Step 2: How to Measure – 5 Key Points
Have your child stand naturally with feet together, arms relaxed, and without shoes.

A. Height
Measure from the top of the head straight down to the floor (barefoot).
B. Hollow to Floor
Measure from the center of the collarbone (the “hollow”) straight down to the floor. This determines dress length and train style.
C. Bust
Wrap the tape around the fullest part of the chest. Keep the tape level and snug—but not tight. Leave room for one finger.
D. Waist
Find the natural waist (usually the narrowest part, just above the belly button). Measure around it comfortably.
E. Hips
Measure around the fullest part of the hips (typically 7–9 inches below the waist). Ensure your child’s feet are together.
