Jess was already very slim. A 20 lbs weight loss on her would have left her with no booty and less boobs. If she lost 20 lbs for this role, but yet in this pic, she looks more shapely than before, then its obvious that its either camera angels and body positioning, padded bra and panties, or implants.
I think its camera angles and body positioning, but anyway.......
