Mirror selfies are a great way to capture an awesome outfit or good hair day, especially if you have no one to take your picture for you. To master the mirror selfie, start with an organized space, the right size mirror, and good lighting. Then, choose a flattering pose and decide what kind of selfie you want, like one without your phone showing, for instance. Now get ready for your personal photo shoot! Wipe it down with a cloth and glass cleaner to get rid of any smudges or spots.
