I find it odd that people have specific clothes set aside for use only while sleeping.  They serve no other purpose and can't be used at any other time.  Most times, these clothes are normal clothes that have been retired from everyday use, but are still comfortable enough to be useful.  But I also know people who actually go out and spend money on sleeping clothes, which to me seems comparable to pouring coffee directly into the toilet instead of letting it pass through your body first. #lifestyle
