Sizing Guide
Little details, for a comfortable fit.

From everyday adventures to special occasions, we want your little one to feel comfortable in their Kidz Exclusive outfit.
Children grow at their own pace, so age labels are a starting point. Taking a few simple measurements can help you choose with confidence.
Always check the size guide on the individual product page before ordering. Sizing and fit can vary between styles and collections.
___
Before you begin:
You’ll need a soft measuring tape and somewhere to note the measurements. No measuring tape? Use a piece of string, then measure it against a ruler.
Check whether the product’s size guide lists body measurements or garment measurements:
- Body measurements are taken directly around your child.
- Garment measurements are taken from the clothing itself, usually laid flat.
These are different: clothing needs room for movement, so a garment’s measurements will usually be larger than the body it fits.
How to measure your child:
Measure over lightweight, close-fitting clothing, with your child standing naturally. Keep the tape comfortably snug without pulling it tight.
- Height
With shoes off, measure from the top of their head to the floor, with their feet together and back against a wall.
- Chest
Measure around the fullest part of their chest, just beneath the arms. Keep the tape level across their back.
- Waist
Measure around their natural waist, usually just above the belly button. Ask them to relax their tummy.
- Hips
With their feet together, measure around the fullest part of their hips and bottom.
How to measure a garment:
If the product guide lists garment measurements, compare them with a similar item your child already wears comfortably.
Fasten any buttons or zips, lay the item on a flat surface and smooth it gently without stretching.
Tops, shirts, cardigans & knitwear
- Chest width: measure straight across from underarm to underarm.
- Shoulder width: measure across the back, from one shoulder seam to the other.
- Length: measure from the highest shoulder point beside the neckline to the bottom hem.
- Sleeve length: measure from the shoulder seam to the cuff. For styles without a standard shoulder seam, follow the product’s measuring instructions.
Trousers & shorts
- Waist width: measure straight across the waistband. Keep elastic relaxed unless the product guide says otherwise.
- Outside leg: measure from the top of the waistband down the outside edge to the hem.
- Inside leg: measure from the crotch seam down the inside leg to the hem.
Dresses & skirts
- Dress chest width: measure straight across from underarm to underarm.
- Dress length: measure from the highest shoulder point beside the neckline to the hem.
- Skirt waist width: measure straight across the relaxed waistband.
- Skirt length: measure from the top of the waistband to the hem.
A helpful detail: a flat width is not an all-round measurement. For example, a top measuring 30 cm across the chest is approximately 60 cm around. Compare flat widths with flat widths, and all-round measurements with all-round measurements.
Choosing their size:
Between sizes?
Check all the relevant measurements and any fit notes on the product page. A larger size may offer more room, but check the length, sleeves and waist too.
Buying a matching set?
Check both pieces. Your child may need different amounts of room in the top and bottoms.
Shopping across collections?
Check each item separately, even if your child has worn Kidz Exclusive before. Fabric, stretch and cut can affect the fit.
Buying ahead?
Allow for growth, while keeping the outfit comfortable and practical for when it will be worn.
