Freeing the nipples is more than just a propaganda or the instinctual need by women, it actually has health and aesthetic benefit according to a study.
It was only until fashion became a thing and companies jump in to consumerism that bras start to gain popularity. Women in early civilizations and those from isolated tribes in the mountains didn't find the need for a bra.
Don't you just feel like stripping off your top and your bra off sometimes like how men go shirtless when they hit the bench after a game of basketball? If you're a woman, reality is you will have to face head on with this taboo. Nipples and breasts are highly sexualized and freeing them in front of everybody, especially in front of men will just be considered obscene or sexually provocative.
When you put a strap and a cup on to support your breasts, you're constricting the blood circulation. It's like forcing your breasts to be numb for that time being; making it prude for the meantime. Better circulation, healthier and firmer skin. Thus, firmer skin, perkier breasts.
Jean-Denis Rouillon, a professor at the University of Franche-Comté in Besançon conducted a study to counter the common misconception that wearing bra makes perkier breasts. He studied the breasts of 300 women aged 18 to 35. That's 300 x 2 equals to 600 staggering breasts!
He found out that breasts of women who skipped the bras developed more muscle tissue which eventually provided breasts natural support. He also found out that a lift of 7 millimeters or 0.3-inch occurred to breasts that stopped relying on bras.
Rouillon strongly concluded that, "Medically, physiologically, anatomically – breasts gain no benefit from being denied gravity. On the contrary, they get saggier with a bra.”
If you don't have that much boobs to show off anyway, you can probably pull it off publicly like Kendall Jenner does. Otherwise, you may have to free the nipples only at home.
But who cares right? Press on nipples!
