Washing machine broken?

I think our washing machine is broken. The reason I think this is that apparently everything we put in it shrinks. My shirts, my pants, they all used to fit me fine but they have all shrunk in the past few months and the only reasonable explanation I can think of is that it must be the washing machine.

My belt has shrunk too, I've noticed. I used to put it on the third notch; now I am using the second or even first notch. I've never put my belt in the washer; it must be all the heat and humidity we've experienced this summer that has caused the leather to contract.
