You can use the button on the back of your shirt to easily hang it
We’re going to show you the real purpose of one little thing: the button on the back of the shirts. This strange button has been there for decades, and most people don’t know what it’s for. Don’t worry; we didn’t know either.
There’s a theory that this detail was born among the shirts of old navy sailors, who didn’t always have hangers close for hanging their shirts. In fact, that is its purpose, to help you hang a shirt anywhere without the need of a hanger. Now you can take advantage of this hack and keep your shirts always straight.
