Size Chart

How to Measure
To find the right size, we recommend measuring your child directly — it’s simple, fast, and avoids second-guessing.
Our size chart shows flat-lay blazer measurements (measured across the front of the blazer while lying flat). If you’ve measured your child’s chest or waist around their body, divide that number by 2 before comparing. Since the body has natural curves and the blazer is flat, allow for a small difference — we've already included a bit of room for movement and structure so the fit stays clean and comfortable.
- Wrap a measuring tape under the arms and around the fullest part. Divide by 2 before comparing to the chart.
- Measure around the natural waistline. Again, divide by 2 to match the flat-lay chart.
- From the base of the neck (where a shirt collar sits) to where you want the blazer to end.
All sizes follow Australian standards. Most children wear the size that matches their age — for example, a 6-year-old usually wears a size 6. For longer wear or extra room, it’s fine to size up — our cuts are designed to stay structured either way.

FAQ's
What size should I choose if my child is between sizes?
If your child’s measurements fall between sizes, we recommend sizing up. Our blazers are structured but not tight — so going up a size gives a bit of growing room without compromising the fit.
How do I measure if I don’t have a blazer at home?
No worries! Just measure directly on your child:
– Chest: Under the arms, around the fullest part of the chest
– Waist: Around the natural waistline
– Back Length: From the base of the neck to where you want the blazer to end
Then divide chest and waist by 2 before comparing to our size chart.
Is it better to size up for longer wear?
Yes — if you're buying for an upcoming event but want longer use, sizing up is fine. Our cuts are designed to stay neat on the shoulders and won’t look oversized.
Will the blazer be too tight or restrictive?
Not at all. Even though the chart is based on flat measurements, we’ve already included a little room in the design for movement and structure. The blazer won’t feel tight — just clean and tailored.
Do you offer exchanges if the size doesn’t fit?
Yes — we accept size exchanges as long as the blazer is in original condition. Just reach out to us and we’ll guide you through it quickly. (Refund Policy in Footer)
