Those who have not yet been through the temple still know that once you receive your temple endowment, you are expected to wear temple garments the rest of your life as a reminder of the covenants made in the temple. I’ve posted previously about some of the thoughts these garments brought to mind.
There’s a side effect to temple garments: you don’t throw them away like regular underwear.
It is a pain to dispose of temple garments. They are not to be thrown into trees like college underpants or disposed of like regular underwear. Temple garments are also more expensive than typical underwear: boxers at Costco go for $8.99 for a six-pack, while a single pair of men’s bottoms cost considerably more (and do not, IMHO, provide better manufacturing quality).
The culmination of these and other factors — cost, sacredness, awkwardness of disposal — lead me to believe that Mormons wear their underwear out a lot more than Gentiles. While a pair of Hanes gets tossed following a particularly bad day, temple garments will be worn until they are no longer distinguishable as such. I have limited data to back this up of course, but all this can change, thanks to your participation in our anonymous poll. Please provide this information, which I will present at the next possible Sunstone underpants symposium.
