I love pajamas. I have some really cute pairs from Victoria's Secret that I wear a lot. At night. While I'm home. Like a normal person.
Wearing pajamas while you're running out to the store, or wherever you're off to, is basically saying to the world, "I'm a hideously ugly person who doesn't care about looking decent". It takes just as much time to throw on a pair of jeans as it does to throw on a pair of unflattering pajama pants.
Even if you have the cutest, most stylish pajamas in the world, it is simply not acceptable to wear them outside the comfort of your own home. Ever.
This type of public-pajama-wearing nonsense should be illegal, as far as I'm concerned.
Take the extra five seconds and put on a pair of actual pants before you go somewhere. Please.
That is all.
