That is particularly likely considering she's modeling a fanny pack, which is supposed to be worn at your front or side so its contents are accessible. "Modeling" one on your backside is ridiculous.I'll put money on it not clipping closed in the front. J is just holding it in place
Judging from where J's hands would be in front of her, based on the location of her arms in the picture, they would be at least six or seven inches apart, possibly more. So add that to the fanny pack's 75-inch maximum diameter.
