That is a whole other debate and preference: should they bounce freely? should it be easier to spot younger woman because they have firm breast? should they wear bras to hide droopiness?
wa.... 好彩我仲fit within your standard....hahaha
actually, i think my back is too boney.... my shoulder blades sticks out kinda, it makes tube tops slip...that's why i can't wear those...
i know what you mean.... like 36B compared to 32B.... of course the later one is more 3D lah...
but i think C is the ideal size in my standard...
