My breasts are naturally very saggy, they don't lift themselves at all and I want to change this because it makes me feel insecure. I'm a 36 D usa sized bra and I'm only 16. My breasts have always been very saggy and I do wear a bra on a daily basis. I'm starting to be very insecure about my breasts and I'd like to know if there is anything i could do to lift and stifen my breasts.
