Designed for the In-Between Years

Not kids' clothes. Not adult clothes. Activewear built specifically for girls aged 8-14: the years that matter most.

🛡️

Coverage You Can Trust

No see-through fabric. No riding up. No constant adjusting. Every piece is tested for the bending, stretching and sitting that tween life demands.

Our Story

Created by a mum who
went through this stage too

I created Athletik Tween while watching my daughters move out of kids clothing but not feel ready for teen fashion. Everything we found was either too young or too grown-up, and I realised how much responsibility parents were carrying when choosing what felt appropriate.

So every piece is designed to be comfortable, covered, and easy to wear: clothing that lets them be active and confident without drawing attention or rushing them into a stage they're not ready for.

If you've ever stood in a fitting room unsure what was right, this brand is made to make that decision easier.

Created by a parent first

Coverage comes first

No sheer fabrics, no adult styling, nothing designed to draw unwanted attention

Thoughtfully made

Every piece tested for comfort, movement and all-day wear

Chosen by cautious parents

Often the first purchase when families feel unsure what's appropriate

Questions & Answers

Frequently Asked Questions

The Starter Bundle is available in sizes 8Y, 9Y, 10Y, 11-12Y and 13-14Y. Both the Ivy Long Sleeve and Bella Legging are ordered in the same size. If your daughter is between sizes, we recommend sizing up.

The Starter Bundle is offered as a matched set: both pieces in the same colour (Black, Electric Blue, or Raspberry). This ensures a coordinated look. If you'd like to mix colours, you can purchase each piece individually from our store.

Absolutely. The Bella Legging is designed for active use: it provides flexibility and comfort for sport, while the secure waistband and reliable coverage make it suitable for school too. Many customers report their daughters wear them under school uniforms in winter.

The Ivy Long Sleeve is designed for tween proportions: not scaled-down adult sizing. It features a comfortable stretch and is true to size. It works great as a standalone top or as a layering piece over a singlet or under a hoodie.

We offer a 90-day return policy: because we know she might need a few wears to decide. Items must be returned unworn, unwashed and in original condition with all tags attached. Returns are hassle-free and no rush decisions are needed.

The Starter Bundle qualifies for free standard shipping across Australia (2-4 business days). Express shipping is also available for $15 (1-2 business days).

We understand this is a top concern for mums. The Bella Legging uses a double-layer waistband and a mid-weight performance fabric that is not see-through — even when stretching or bending. We guarantee it. If you're not satisfied, our 90-day return policy means no risk to you.

Yes. Athletik Tween pieces are designed to be worn hard and washed often. The fabric retains its shape, colour and stretch after repeated machine washing. We recommend a cold gentle cycle and air drying to maximise longevity, but many customers machine wash and tumble dry on low with no issues.
