Security ... think about it!
You don't have to sacrifice your looks to protect yourself. Let me tell you about how I protect myself. First and foremost, I carry a gun and a knife with me at all times, and I have taken self-defense classes. I keep myself in shape in case I need to run or fight. I'm extremely vigilant when I go out, keeping an eye out for anything suspicious. I keep myself free of distractions while in public, like cell phones and iPods. I wear sensible footwear and sensible clothing. By "sensible clothing", I mean nothing flashy, expensive, or provocative. I can easily blend into a crowd. Notice how nowhere in the above paragraph did I mention gaining weight, wearing baggy clothing, or generally looking like a hag. If you want to do that stuff, go right ahead, but please don't fall into the trap of believing that you NEED to take those measures in order to be safe. You don't.
