Sonnet 130 is like a love poem turned on its head. Usually, if you were talking about your beloved, you would go out of your way to praise her, to point all the ways that she is the best. In this case, though, Shakespeare spends this poem comparing his mistress's appearance to other things, and then telling us how she doesn't measure up to them. He goes through a whole laundry list, giving us details about the flaws of her body, her smell, even the sound of her voice. Then, at the end, he changes his tune and tells us about his real and complete love for her.
