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 β 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 β completely. No stress, no pressure. Just finding the fit that helps her feel confident, comfortable, and completely herself.
What's in the set
- Bella Legging β full-length, fully opaque, holds its shape
- Izzy Crop β sits at a length she doesn't have to think about
Pick your colours for each piece and the size once. Both arrive in the same size, so there is nothing to work out.
Why these two
This is the pairing our customers reach for most, and the one I'd start with myself. The legging is fully opaque β the thing most parents check first, and the thing our reviews mention more than anything else. The crop sits at a length she can move in without adjusting, which is the difference between something she wears once and something she wears every week.
Together they cover sport, PE, dance and the weekend, without asking her to look older than she is.
