The sides use a stretchy power net. Since it is designed to be high on the sides, it will hold the meat securely and eliminate the difference in level.
The power net that follows the straps lifts up your bust. The cup is carefully designed to follow the bust without raising it. The skin side is fluffy and comfortable.
Even if your bust is small, breast sagging is a concern. The carefully raised structure shows off the lines of your body in the desired position without bulking up your bust.
