The number 1 reason is comfort. This really is more important than many people realize. Comfort affects more of a woman’s life with this undergarment than many men and women realize. The amount of time women spend struggling to make a badly fitting bra work, and the constant mental drain of dealing with a badly fitting, uncomfortable bra is amazing once finding a properly fitting bra is done. It actually is a bit life changing-I am not exaggerating this. Less pain, better posture, fewer back, neck and headaches.
A properly fitting bra isn’t near as uncomfortable as people make out. When your bra fits properly, you don’t get chaffing, rashes, sore shoulders, poked by the underwires, and it can improve your posture. No, I am not exaggerating any of this.
A poorly fitting bra can shift, jab, and chaff. It will move up between your shoulder blades, rub you raw in the front, dig into your shoulders, and move around under your clothing. Imagine underpants that did all of that? If your underpants were shifting, chaffing, and jabbing you-you would get a different pair or go without them right? Why would you think something that is designed to support and be worn under clothing on the upper half of your body should be different?
A properly fitting bra is also less likely to be painful. The majority of your breast support should come from the band around the ribcage, not the shoulder straps. Sadly, most wear bras that are trying to do the opposite, support from the straps. This can cause dents in the shoulders of a woman if it goes on long enough. It can also lead to slouching to try to relieve the pressure. Slouching leads to a sore back and bad posture. Think of how it feels when you carry a heavy shoulder bag any length of time, now consider how it would feel to carry a heavy shoulder bag on both shoulders for 8+ hours a day. It is the same thing with an improperly fitting bra. If the band is too big, it can also allow the breasts to fall out the bottom of the bra, leading to constant shifting of the breast to put it back in the bra or bad posture to try to keep the breast in the bra cup. If the band is too small, you can get “rug burn” from the chaffing and pressure when you move through out the day, not to mention the bulges in places you don’t want them.
If you wear underwired bras, a proper fit in both band and cup size is VITAL. If the band is too big or small, the underwires will poke into your breasts, ribs, armpits. The underwires will also not sit properly on the body. They should lie flat against the ribcage and sternum. If the cup size is too small the underwires will also pinch or poke the breast tissue, and you can have “muffin top” where the breast overflows the top of the cup-not a good look. If the cup size is too big with an underwire, you will not only have the jabbing and poking, you will have shifting and lumps. Again the underwire will not sit smoothly against the body and can slide with every movement you make. The underwire will also not be able to properly “prop up” the breast, leading to it sagging and looking saggy.

The above shows how a bra should fit and the difference it can make, notice the posture is better and part of a good fitting bra is that it does NOT shift with movement?
And finally, since you rarely see it mentioned, a good, properly fitting bra boosts confidence. It’s not just about breast size or fullness, it is about how you carry yourself. When you can stand up straight, feel good in your clothing, and not worry about constantly adjusting, shifting, or worrying about spilling from a bra, you are free to concentrate on other aspects of life that make you feel good about yourself. The lack of wasted mental energy needed when you have a properly fitting bra frees you up more than most realize.
