It's too warm in Florida to wear long pants, so shorts are my regular riding attire. The exception is on very rare, cold days, 50º, then I wear jeans with trouser clips. I had to get them, online, and what I got was designed by a bloke with rectangular cross section ankles. The photo showed round clips but what came were clips that would fit a 2" x 3" wood stud. Seriously! I had to use pliers to make them round, and that wasn't easy because they were spring steel.
I wore clips when I was young, but I never thought about wearing only the right one. I like to feel balanced, and one clip would have felt unbalanced.
... and use a distinctive handshake?
I never knew a Freemason to wear trouser clips, but I suppose some do. I've been there in the weird Masonic clothing for the three degrees. Out of it, now, though.
