Beep Beep Beep

I keep forgetting to do my flies up lately. It's very easily done, and people take offence to it when they notice. I think a more advanced pair of jeans would alert you to this, with a buzzer that doesn't stop until they're done up, you know, like the seatbelt alert in cars. It could also prove effective in the prevention of flashers.

I have many more ways to improve trousers, which I shall bring to your attention at my earliest convenience.
