Our Fit

Designed for wedgie proof ultimate comfort

Our full coverage undies are designed to fit the natural curves of your body so they sit comfortably in the crease of the leg.

Find out more about how each style fits through our size guide.

No Elastic

We use the same soft organic cotton blend to cut our binding instead of using elastic, so they don’t cut into your bum. 

Wedgie Proof

The cut puts our undies in the right place on your body for maximum comfort, and the fabric keeps them there, so they don’t ride up or move about.

90% Cotton / 0% Spandex

We use our own blend of 90/10 organic cotton fabric that hugs the body without stretching or bagging.

Our Fabrics & Prints

Our GOT certified organic cotton/spandex fabric is custom milled in AU and LA to our exact specifications. It is sturdy, very stretchy, and has great retention -to give our undies just enough stretch and bounce back to stay up and on. We use nylon thread so that your undies have enough stretch around the seams to get on and off with comfort.
