Jackie is seriously down in the dumps after yet another friend has found love and had a gorgeous wedding. Wanting to help lift her spirits and increase their odds in getting attention from men (and since they're all dressed up anyway), the girls take themselves to a fancy hotel where a convention of BBWs (""Big Beautiful Women,"" i.e., ""fat chicks"") is hosting a formal dinner and dance. Maybe in comparison, Jackie and friends will be thought more attractive by any men in the area. Big Fun in discovering size has little to do with sexiness: it's all in the attitude, and it begins with liking oneself.
