Don't you hate when your pocket square falls into your pocket and nobody can see it? Well I do.
Here's a quick and simple solution: pin it in place.
I usually do this with a simple lapel pin (the ones with the small gold clip on the backside). Reach down inside your breast pocket and stick the pin through your folded (or "puffy") pocket square and through the inside of your pocket so that the small clip is on the inside of your jacket.
For those who don't like the idea of making a small hole in your jacket lining, the same trick can be accomplished using small magnets.
There you go, no more pesky disappearing pocket accessories.
Yours in style, SB
