Semiotics in the air

The Family assures me that I’m wrong about this sign in front of my seat on one of the new Airbus A320 Neos. but I’m not so sure. I puzzled about it for a while, before I discarded the idea that this shows where to look for blond wigs. I think Airbus has put stowage space under each seat for women’s underwear. I think I should find it outrageous that they have not provided for men’s underwear. I looked at the signs in front of some of the other seats too, so it’s the whole plane.
