Many guys would do anything to get a rounder butt. I know I've had my days when I wish I had a "bubble-butt". Well now Andrew Christian has developed new butt lifting technology that promises to do just that. But this rear-enhancing brief is much different than the other ones out there. Instead of using padding, cups, or straps that are hidden inside, this brief features an invisible lifting support built into the seams of the underwear. The construction of the underwear automatically lifts the buttocks making it look firm and round. AC claims that most people can add up to 1/2 to 1 inches onto their current buttocks measurements. So if you've been longing for that perfectly shaped butt, hold off on the gym and try out these briefs first. Let us know how they work.
