premise: However there was one pair of black capris that I knew should fit me . They were very tight on me last year , so I thought , oh yeah they will definetely fit me this year . So I pulled them on thinking I could still wear these to work , but as soon as I had the zipper done up and let go , they dropped back to the ground . So in the long run . Why will the capris definitely fit me this year ?
hypothesis: Because I 've lost weight .
