The British department store Marks & Spencer have started selling their new "bum lift" and "frontal enhancement" underwear. They have developed and released two styles to help guys who want a little booty bump and more impressive looking package.
The three pictures below show how the new design works. The first picture is regular underwear. The second with the "frontal enhancement" and the third with the "bum lift".
And then Marks & Spencer has released how exactly the design works (shown in the below diagrams).
