What is an example of simile in the book, All I Want Is Everything: A Gossip Girl Novel?

Simile:

"If boys were like clothes, the way Ms. Doherty said, then Nate was like her first pair of Diesel jeans that she'd bought and only worn on special occasions because they were so nice...but the more she wore them and the more she washed them, the better they fit, until it got so she couldn't live without them - they were the perfect fit."
