Prima brought our attention to the niftiest invention. It's a mirror that's capable of telling you your bra size! All you have to do is stand in front of it with any bra on and slowly turn around. Then it will take over 140 measurements of your body and tell you which bra size is the right one for you! Check out the video:

Would you let a 3D mirror take your measurements? If so, then you should visit Rigby & Peller in London. They have one of these mirrors right inside of their store for their customers to use. Hopefully, these mirrors will be brought to the US soon.
