Q: When is a fanny pack ok to wear?

A: When you call it a belt with pockets and you make it really expensive.

$180 Slvr Men's pocket belt
This is a way for men to have purses or extra pockets I guess now that everyone is wearing tightass skinny jeans.
It would take a certain kind of guy to pull this off, but it wouldn't automatically look dumb like most fanny packs.
