Aside from a push-up style, which aims to give a fuller look, the primary purpose of bras is to lift breasts and keep them in a position that works for the type of look you want to wear.
Health Benefits of Wearing a Bra
From a breast-health perspective, Dr. Teplinsky confirms that wearing a well-fitted, supportive bra can reduce breast pain (also known as mastalgia). "A sports bra during exercise can reduce pain related to breast movement," she says. "Wearing a supportive bra at night can stop the breast pulling down on the chest wall, support the breast, and can help with sleep."
