A lesson I learnt to my dismay is that if it looks big, it may not be big. Bras come in full cup and half cup and quarter cup. If it is a fitting bra, there should be some bouncing when the lady is walking. If there is none, that means that she is probably wearing a cup too large and her boobs are fully contained within the cup, so her boobs are actually smaller than it may appear. And you also have miracle padded bra which throw everything out of whack. It appears very normal until taken off, so there is really not much method to tell, except for the side view full bounce
