Octopi Cannot Wear Pants

Imagine a world where octopi evolved to walk among us. They are able to breathe air, walk around on the ground, and no longer need water to survive. Now, I think that would be pretty cool except for one major problem that I have identified.

Do you know where an octopi's buttock is? On their head. Therefore, there is no way they would be able to wear pants! While it would be cool to walk outside and just see an octopus walking around in the wild, but they would never be able to truly assimilate into society. They would be the outcasts that cannot wear pants.
