They generally don't specify measurements it's more like if a model fails to maintain appearance (not just gaining weight, but loosing weight, changing hair drastically, piercings, obvious tattoos, eyebrow waxing etc) the agency can drop them. But I doubt IMG's about to drop a VS angel who's probably making way more than any of their 34" hip girlsdont modeling contracts state that you can't go over a certain measurement? she's way past those requirements i believe unless she's plus now
