Tiny Speedo

You wear as little as the rules allow, and tug the tiny speedo that is clearly a size too small onto your body. Your package strains against the material already, and all eyes are on your groin as you approach the ring, each step bouncing your obvious bulge. This will definitely serve as a distraction and make it trivial to weaponize your bulge, but could also highlight an obvious target for your opponent to attack.
