Measure the body (not the garment).
If between sizes, we recommend sizing up for comfort.
How do I choose the right size?
We've aligned our sizing with Australian standards, but every girl grows differently, especially in the in-between years. We recommend choosing based on how she likes to feel: snug and supported or a little more relaxed.
What if I'm unsure about sizing?
You're not alone — most mums are navigating this stage too. If you're between sizes or unsure, we suggest sizing up for a longer-lasting fit and extra comfort.
Will it fit as she grows?
Our pieces are designed with flexibility, stretch, and movement in mind, so they adapt to her body and keep her comfortable as she grows and moves.
What if the size isn't right?
We've got you. We offer a 30-day return policy, so if something doesn't feel quite right, you can exchange or return it with ease.
Is it really risk-free?
Yes — completely. No stress, no pressure. Just finding the fit that helps her feel confident, comfortable, and completely herself.

Fabric and performance
Made from recycled polyester/elastane, the Ivy Long Sleeve is built for performance and all-day comfort.
