But the use of the clip may not be doing anything to keep the breast firm, but rather the opposite.

This is one of the preliminary results of an experiment conducted for more than fifteen years in the University Hospital of Besançon by Professor Jean-Denis Rouillon.

     "Our first results confirm the hypothesis that the bra is a necessity false. Medically, physiologically and anatomically female breasts do not benefit from the deprivation of gravity. Instead, languishes with bra".

The chest tone and win support for himself if not used bra. Use the clip implies that "not only supporting tissues are not developed but even atrophy and chest slowly degrades."

Professor Rouillon has been conducting his experiment since 1997, measuring and examining the breasts of 330 volunteers aged 18 to 35 years, using a slide rule and a clamp to record the change in position of the breasts with age.

Rouillon states that during the investigation amounted thought about 7mm nipple on men in a year when women who wore no bra. The chest became firmer and stretch marks disappeared.
"It would be dangerous to advise all women to stop using her bra as women who participated in the study are not a representative sample of the population," said verbatim Rouillon, a French magazine The Connexion.
