36DDD: Having 1lb Removed From Each Breast - What Cup Size Will I be?

I agree with the other responses but I express it differently. This is the opposite of the question, "what size will I be if I have a 500 cc breast implant put in ?" There is not only no standard for breasts in terms of cup sizes but there is no way to know how much a given volume of breast tissue will weigh until it's removed. If it's fatty breast tissue it will weigh less and if it's dense glandular breast tissue then it will weigh more. 

The way to approach this is to agree on the general cup size for your chest around that is the goal in terms of volume/size. The surgeon should remove the appropriate breast tissue from each breast to leave a breast of that size and then send the tissue to be weighed and find out how much it was in lbs. or gms. You don't want to start from the weight and work backwards any more than you want to start from the number of cc's and work forward in a breast augmentation. 

Unfortunately, there is no direct correlation between the amount of tissue removed and the ultimate cup size that a patient will wear after breast reduction surgery.

Before undergoing the breast reduction procedure it is very important to communicate your size goals with your surgeon.  In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or “C cup” or "fake looking" means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.

Best wishes.

It is difficult to predict an exact cup size after breast reduction.  The cup sizes are not objective measurements and many women may minimize their preoperative cup size to begin with.  The goal of a breast reduction is to remove breast tissue safely to help minimize symptoms of neck pain , back pain,shoulder grooving etc.  IT is not an exact science and it may be difficult to predict exact cup sizes post op. Discuss this issue with your plastic surgeon.

No one can tell you accurately what your cup size will be following your breast reduction.  First of all there is no standardization of cup sizes and there is a good bit of variation among different manufacturers.  Having said that, my best guess is that you would be in the neighborhood of a D cup with removal of 450 grams from each breast since you are currently wearing a DDD bra.
