You keep refering to DDD size bras. Are you aware that DDD and E are both the same cup size? This may help you to know when you go bra shopping.
I am a full DD. when they were put in the swelling had me looking like a full F cup.
When I had mine done my chest was ENOURMOUS! But about 4 weeks later the swelling went down and the implants settled. Id say they lost about 2 cup sizes after healing. So dont fret...youll love em in a little while.
