Don't be shy. You know you want to cut loose and gyrate those hips like the King of Rock and Roll. If you just go around shaking those things in public, all willy nilly, people might get a little weirded out. However, if you do it dressed like Elvis Presley in a gold jacket and pants set like this one, everyone just screams and faints. It's your choice though: screaming fans, or complete awkwardness.
