So there is no really any proven theory that wearing bra will cause breast sagging nor help in preventing it. Then i decide to ask my girl friend for help, and they are all very helpful in this kind of matter. I will conclude all the related answer and the correct way to choose a bra according to my findings.


Picture of several breast shape that women have
First is the breast tissue. I find that every girl have different breast tissue orientation. Some have fuller breast, some have pointy breast, some have fuller in bottom breast....all and all, the bra need to match those pair of breast. To choose a correct bra, one must know what is the shape of their breast first, just then you will know what kind of bra is suitable to wear.
Second, choose the correct design of bra. Bra comes in different design, let alone the material that is use to produce the bra. Choose the correct design first, just then choose the material. The correct design will provide the needed support to the shape of the breast. For example, if a breast is fuller on bottom, then to produce a nice view, the bra will need to have a infill support at the cup, so that the fuller bottom breast will have the breast tissue push upward and fill in the upper cup thus produce a better view under cloth. If the cup does not have infill, the upper breast won't fill the upper cup and there will be a gap between the bra and breast. Then the looks of the breast and bra will become significant and ugly under cloth.

Third, choose the right size of the bra. This is the major problem every women face. All my girl friend does not know how to properly choose the correct size of the bra. And all of them who i have talk to say to me, they depend on the sales lady to fitted for them, or they just try and see if the bra fit properly. Well, after i search on this subject on line, i found many Bra Calculator available for use. And i ask my wife to try several calculator and the size is not very convincing. I have work around the correct way to calculate the size of bra:

Before taking the measurement, it is advise to take off the bra you wearing.
1. take measurement under bust
2. take measurement over bust
3. deduce the difference between the 2 measurement
4. find the correct cup size below

The under bust size will be your primary band size. If the measurement come with 33 inches, then the suitable band size will be 80/34. And when the over bust measurement come as 36 inches, deduce the 2, will get 3 inches, then the should be correct bra size is 80/34 C. Why i say should be correct, this is because the size you calculated is not 100% suitable to the shape of your breast. If you have a wide apart breast, and the measurement comes in as above, then you probably will need to try 85/36 B, this is because the wide apart breast shape will have a wider breast tissue, and a bigger size bra will hold the breast tissue in place. Smaller bra will squeeze the wide breast tissue closer together then it will make the breast sore. This is when, for a wide breast shape women, it is advise to try Plunge Bra, as this bra is design for wide apart breast shape. For this Plunge Bra, the size will be 80/34 C. And this bra is very comfortable for wide breast shape women.

Also do take note, if the size of bra is 80/34 C, moving up a band size will require to reduce the cup size like this: 80/34 C > 85/36 B > 90/38 A
And moving down a band size, the cup size will be increase: 80/34 C > 75/32 D > 70/30 E
As of now, it is clear that the bra size is very dependable on the shape of breast one have. If the design of bra is not suitable to wear on the shape of breast, then the size will only make things worse. This is why many women does not wear a correct bra the whole life.
So the question still haven't be answered. Do wear bra for a prolonged period will make breast sagging? The answer is NO, and for not wearing bra will make the breast sag? The answer is still NO. The sagging of breast is depend of the shape of breast one have. The much higher risk to have a sag breast is those that have a fuller on bottom breast, point down breast, and those that have a weak upper breast muscle. For this condition women, i advise is choose the correct bra, and avoid wearing a soft cup and unwire bra.
So for any question or any parts that i forgot to mention or not mention clearly please do leave a comment below.
