The argument is that your stuffed animals are regulated, mattresses and pillows are controlled, and chair stuffing has legal restrictions, but padded bras fly under the radar. Most 'hygenic' padded objects require only new materials be used in the manufacturing, but your boobie ballast might be shredded hotel blankets. The industry, of course, thinks the limitations are crazy because so little padding is used, but if they cared about breasts as much as I do, they'd understand just how fucking important it is to be nice to a lady's tits.
