Well that's the aussie term for them!

I'm looking for this addition to my loungewear. I have a mid blue hoodie I'd like to wear it with. The hoodie isn't too long so I want it to look ok around the hip/thigh area (which I'm a bit sensitive about). I tried on one yesterday in Cotton On which had pockets and look ghastly as the outline of the pocket could be clearly seen.

Any recommendations?
