What’s a budding girl of Scandinavian stock like 21 year-old Isabella to do? Take off her bra. A professor at Sweden’s Lund University advises young girls to not wear bras too early, because of the chance of creating low-hanging breasts. “Too tight a bra can lead to breasts that sink,” warns the prof. “If natural movement is restricted by a bra that is too tight, it can affect the growth of elastic tissues that naturally support the breasts. Bras caused nipple height to sink slightly.” He cites a French study of women from 18 to 25 that claims that the distance between a woman’s nipples and the ground decreased in women who wore bras.
