Most of you might have had the experience yourself – you go into H&M, find a garment you like, and head for the dressing rooms. In the dressing rooms there are two mirrors. One of them shows you just as you are, the other makes you look thinner and taller.
The photo to the left shows me in the magic mirror. The one to the right is me in the normal mirror (with the magic mirror in the background).
Smart thinking from H&M. I bet they sell loads more than if they just had one normal mirror.
