What do you think of my speech?

I would think you could get a better topic. Does modesty really matter? Did it ever save somebody's life? Did a lack of modesty ever kill, maim, or starve someone? So, I think what you've done is fallen into the trap of fashion provocateurs. They want you to give this speech because it means, contrary to what your speech says, that the way they dress really matters. They got you so worked up you gave a speech about it. Come on, you can go better. Let them wear--or not wear--what they want. Go on to important things. Of course they look like jerks. But who cares?
