i got Minnies buddy belt today too !!! hers doesnt fit as good as i'd like it too either. i tried Lattes size 2 on her and it buckeled on the first hole but was not comfy on her. so , i ordered the size 3 and it buckles on the 4th hole loose. i think it would buckle on the tightest hole, the 5th hole snug. i think it will fit nicer over clothes though. i'm happy with it, i'm not sending it back.
i love the pics of Kai, she's so pretty and the buddy belt looks nice on her, its a pretty color ! are you going to keep it, cause you said you werent happy with the fit?
