Huge boobs can look so incredibly sexy yet require adaptions from normal walking. Your upright posture to balance the front heavy weight now inhibits taking anything but a short stride, which may look like baby steps to the casual observer, and wearing heels only amplifies this effect, one foot barely landing past another. Of course, the short steps, while aiding in your balance, do produce more bounce and sway, feelings that you love. Your arms no longer swing like a normal person when walking because your sideboobs prevent such movement and you feel the need to often extend them a bit, especially when trying to walk quickly, to aid in your top heavy balance. The higher and larger your boobs are, the further your line of sight of the floor in front of you becomes and when your boobs start reaching the desired size, you find you cannot bend over far enough to see your feet. Even bending forward nominally not only adds strain on your back, but threatens your balance past a certain point, and creating a need to bend at the knees when reaching for lower things. So your movements become more prim and proper, always carefully restrained, always looking more lady like.
