I, too, have breasts that are disproportionately large, given my body frame. I was heavier in my 20s and had really big breasts, but even at about 120 pounds and small clothing sizes now, I'm a 32DD. It does make clothes shopping difficult sometimes.

For anyone who can't or doesn't want to get a breast reduction, I highly, highly recommend weight training, particularly exercises focused on the back muscles. I started a few years ago, and I no longer have any issues with the back/neck pain I used to get from carrying around these boobs. I had posture issues before I started lifting weights; a year after I started, I measured a half inch taller at my doctor's office, it had improved so much. (I was 30 at the time, so I hadn't grown!)
