This reminds me a bit of those disentanglement puzzles where you have to think about the topography of the pieces...it almost seems like a mobius strip, but there are definitely two sides and not one. What am I not seeing here?

I was doing the laundry this morning and noticed a pair of underwear got twisted in a weird way. I spent a few minutes trying to fix them--turning them inside out, flipping them around--but nothing worked! Metafilter, please help me untwist these knickers.
