Approximate Cup Size for 339cc Breast Implants on B Cups?

I am 5'5", 118 pounds, 32b cup. I'm considering 339cc or 371cc Allergan Mid profile smooth round Breast implants, and I will be going under the muscle.

I want to look natural. I know from reading these questions that I can't get hung up on cup size, but could you approximate what size I will be?

Also, why do some doctors say you lose volume going under the muscle and others say you don't lose anything?

Estimating bra cup size after breast augmentation

Hi Govswife - It sounds like you may be a large C/small D cup after getting the implants that you described. Right after the surgery, you will be swollen for about 4-6 weeks so your cup size may come down some. If you really want to know, place some implant samples in your bra or different bras to see how big you will be. Good luck!

339cc Breast Implants

While it is difficult to nail down the exact breast cup size, you probably will be in the "D" cup range for the volume you are adding to your present "B" cup.

339 cc breast implants should give you about a full C cup

371 cc will start to push you into the small "D" cup which might look less natural and more "implanted". If you are trying to have a natural look I would suggest the smaller of the sizes. Of course it is a little difficult to say for sure without seeing you in person but that is just a generalization. As far as losing volume when under the muscle, I don't know why some doctors have said that. If you are trying on implants inside of a bra, you can expect the size to be a... more

Use a sizer for approximating breast implant size

It sounds to me that you would end up in the range of a full C-cup, but this is really not as important as whether or not you are happy with the size and shape of your breasts with this implant. Remember that cup size is subjective and in fact you can find different brands of bras with cup sizes ranging from B to D that will literally fit the same size breast. It is most important to be pleased with the general form of your body rather than getting hung up on the size of implant or the... more

Predicitng cup size

Given that the volume you describe is about 1.5 cup sizes and given that 32 band width bras go up faster in cup size, I will guess you might fit into a 32 D after.

Bra size estimation

With your height and weight as well as the 32 band size on your bra you will get a distinct increase in your bra cup size with the implants that you have chosen. I think it is a good choice by the information you gave me. With a 32 band size the cup size goes up quickly so you could easily be a D size cup with the implants. If you used a 34 band size then you might stay a full C. This is my estimation by what you have shared. Another thing to consider is the base width of the implants and... more

Best guess

My best guess is that you will be around a full C cup. Obviously, you are going with silicone which gives a softer and smaller appearing breast compared to saline implants. When you augment the breast they get larger, regardless of over vs. under. Given the same implant however, under the muscle may or may not appear a bit smaller, but in my opinion, the benefits of going under the muscle outweigh the negatives. You are right not to hang up on cup size as bra sizing in not standard. The... more

Cup size

You will probably by a high C, low D cup BUT remember it is not the cup size that matters, its the look. I find that one of the best ways to determine the right size implants are as follows: 1. Have the patient try on the implants in a stretch bra with a clingy top to obtain the look they want (if you want a "C" cup put on a "C" cup bra) 2. Have the patient show the doctor pictures of how they want to look 3. The surgeon should be able to put that information together to... more

Breast implants

The way I like to do breast augmentation is with sizers. I have a cup size or photo from the patient and then by using sizers I can see which implant will give the size my patient wants. Stuffing implants or rice bags under a bra is not an accurate way of determining implant size.

Breast implant size

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... more

339cc implants and breast size

The best test for you at home is to take some rice and place it in nylon stockings. Grams are about the same volume as cc. Put 339cc (ie grams) in one stocking and 371 cc (ie grams) in the other stocking. This amount of precision is not possible with plastic surgery, but we, as many others, size you in double bras (tighter on the outside, and insert implants until the look you like appears). Do not force the surgeon to place exactly that volume, for at surgery, conditions change. He or... more
