Because Guys Don't Have Enough Reasons to Look at Your Chest
You really should install a bra with flashing swirling neon lights.
I'm not sure if "install" is the correct term to use for a bra; but I have never really performed the act, in that direction. This one has lights, so I'm counting it as an appliance/electrical device.
The only downside for attention whores wearing one is they can't compete in any wet T-shirt contests. Though, I'm sure if they did, it would create a lot of attention.
