Some answers ...

How do I work out my size?

We've worked on our sizing tips and chart pretty well ... so check it out on our sizing page under the INFO tab.

If you need more assistance, please email us at

What are the smallest and biggest size you make?

Womens from size 8 Au to size 16-18 Au

Mens from size SM Au to size XXL Au

What's the difference between Low-rise, Regular fit and High-top?

The original regular fit sits around your waist - about an inch and a half below your belly button. The Low-rise sits around an inch and a half below that of the Regular fit. The High-top sits around an inch and a half above the regular fit.

Do you custom make Wonderpants?

No we don't. Just the fabulous collection of Wonderpants that is available through our online shop.

Do Wonderpants have elastic in them?

No. Wonderpants are made entirely from the same fabric (no elastic and no binding, no part tight or uncomfortable), the bands around the waist and leg allow for comfort and ease, whilst maintaining stability and security. 

What fabric do you use for Wonderpants?

Wonderpants are made from high quality Australian made Organic cotton with elastane. The mix is 92% organic cotton 8% elastane.

Why elastane?

Without elastane, your Wonderpants would become a baggy, saggy waste of time very quickly, and rather than filling your top drawer with your new beloved comfy knickers, we'd be filling your cupboards with extra cleaning cloths - you would not be happy - and neither would we.

How should I care for my Wonderpants?

We recommend, to keep a long healthy life for your wonderpants, to wash on gentle cycle, using eco-friendly detergents. Hand washing also recommended if you have the time. We recommend utilising the power of the sun to dry - and not the use of dryers - your Wonderpants may shrink, and you will not be happy about that.

Can I return my Wonderpants if they don't fit?

Yes you can. We have a generous returns/exchanges policy. See our customer services page for details.
