Theoretically, a pocket mirror can be used for grooming--you keep it in your bag (or your pocket! Hey, baby--I can see myself in your pants), and you pull it out occasionally when you want to make sure that you don't have anything in your teeth, or you need to reapply your gloss and do not have the kind of powers Molly Ringwald did in The Breakfast Club and can't just put it on with your breasts. If it is not for simple grooming tasks, then it can be used for checking exactly how pretty you are, which is always nice to be reminded of. An exceptionally fancy and very pretty pocket mirror, like these from the Charm Lady etsy boutique, can make all these tasks pleasant, and your life that much lovelier all around.

But--and this is important--it can also be used for super secret spy missions. Peer around corners! Look at the people behind you on the bus! Reflect light into unsuspecting evil-doers' eyes and foil their schemes! Burn through the ropes that are holding you suspended above the piranha tank and make your spectacular, unexpected escape! And then, you can check and confirm that you are not only a badass, but still so totally hot.
