Task: Question Answering
Input (English): Context: So we 're officially down to seven days before the big race and I ' m so doing the typical Janice thing by trying to cram as many miles in as possible at this very late stage . Our team gear arrived in Hollywood fashion at Shem 's place on Saturday morning - And with the cropped tri top and tri shorty being the only outfit that fit me , I ' m feeling all self - conscious about the unwanted spillage that 's happening around my mid - section these days . I have entered the secondary thickening stage and I so refuse to get sucked in . 
Question: What may be the reason why their clothes do n't fit them ?
Output (English): They have gained weight .
