I wear mine occasionaly out to dinner with the missus
And when I take my twice yearly trip to the casino. All my suits have pin stripes, although I am in the market for a nice plain grey suit.
I once held the door open for an elderly couple in Vegas(cause I'm just that kinda guy :P) and they must have thought I was a doorman and slipped me a $20. I kinda felt bad, but it went to good use on the four card poker table.
And ties must have stripes!
