Time Travel...
... Is not as impossible as they make it look. It's a portable device that can literally fit in your pocket.
While we kid about it, the truth is that a simple kerchief can transport you to a time when kerchiefs & pocket squares were functional & style.
In ancient Greece, silk squares were infused with fragrances. In Egypt, they were hidden out of sight only to be revealed to be used as wipes. The Indian men used the trusted Rumal to cover their heads or roll up notes.
The simple kerchief today carries the responsibility of doing all that & adding a pop to any ensemble.
