If you are facing a mirror, look straight ahead, do not look at the lens of the camera, or look away. Establish eye contact with yourself. In the photo, it is the perfect way to achieve it.(

Try to move the cell phone away from your body and pose. The idea is that later You can zoom in and cut the hand where the cellphone is seen, in this way the photo will be more interesting.3
If you want to show the complete outfit, stand in front of the mirror, lower the phone to the height of the hip, raise the camera a little, pose and have the shot. The result will be much better. In the photo I show how it should not be done.
