I love these undies - my favourite fit! I originally bought a medium (my regular size) but found it stretched after one wear and the pad area was too large. Exchanged for a size small and they fit perfectly. Seriously, the most comfortable pair of underwear I own!!!

I only wear Knix underwear. So many styles and colours to choose from. Great fit and fabric.
They last a long time so are worth every penny.
